General Chemistry Notes-4


Calcination is heating strongly in the absence of air. Roasting is heating in the excess of air . Smelting, also called autoreduction, involves reduction of ores, usually oxides at elevated temperatures.


It is difficult to remove the earthy matter called gangue which contaminates an ore. This is done by adding to ore a substance called flux. Flux combines with gangue to form a molten product called slag, which can be easily removed.

An alloy is a mixture of two or more metals and is homogeneous in nature. For example Brass (Copper, Zinc), Bronze ( Copper, Tin) and Gun Metal ( Copper, Tin and Zinc) are examples of alloys.

An amalgam is a solution of metal in mercury. Sodium amalgam is used a reducing agent. Tin amalgam is used for making mirrors. Cadmium and Gold amalgam are used in dentistry.

A few elements like arsenic, Antimony, Boron, Silicon and Germanium behave both like metals and non-metals. These are called metalloids.

The five main causes of air pollution are carbon monoxides, nitrogen oxides, hydrocarbons and sulphur oxides. Transportation sources are responsible for 74% of all carbon monoxide emissions. Use of Catalytic converter in two stages helps in eliminating pollutants from exhaust gases before they are discharged into atmosphere. In the first stage converter, Nitrogen Oxide is converted to Nitrogen and Ammonia in the presence of finally divided Platinum as a catalyst. In the second stage coverter, Hydrocarbons and carbon monoxide are completely oxidized to water and carbon dioxide in the presence of Platinum catalyst. Unleaded gasoline should be used as Platinum can be poisoned by the lead.

Much of Nitrogen Oxides and Sulphur Oxides entering into the atmosphere are converted into Nitric acid and Sulphuric acid. This will generate precipitation known as acid rain.

Urea is used as a fertilizer. DDT ( Dichloro-Di-Phenyl Trichloro Ethane) and BHC ( Benzene HexaChloride) , Melathion and parathion are used as pesticides. Zinc Phosphate and Barium Carbonate are used as rodenticides. Bordeaux Mixture ( copper Sulphate + Lime + Water) are used as fungicides.

1. Ammonia is manufactured by the Haber Process



2. Full Name of TNT, an explosive is Trinitrotoluene



3. Trinitrophenol, which is used as an explosive and antiseptic is also known as Picric Acid.



4. Nessler’s Reagent is used for the test of Ammonia and Ammonium Salt. It gives brown precipitates



5. Nitric Acid ( HNO3) is manufactured by Electric Arc Process.



6. The process of Petroleum refining is called as a fractional distillation



7. There are various products having different boiling points which are obtained during fractional distillation. At a boiling point of 30 to 70 celcius there is Petroleum Ether which is used as solvent for drycleaning. At a boiling point of 70 to 120 degrees celcius, there is Petrol or gasoline which is used as a motor fuel and general solvent. At a boiling point of 120 to 150 degrees celcius, there is Benzoline which is also a solvent. Then there is Kerosene at 150 to 300 degrees celcius which is used as an illuminant and as a fuel. And Finally above 300 degrees celcius as boiling point, we have Lubricating oil, vasaline and paraffin wax which are used as lubricant, grease and wax.



8. Petrol is obtained by a process called cracking. In this process kerosene and crude oil are broken up into low boiling point hydrocarbons such as Octane and Heptane.



9. To prevent knocking in petrol engine, an antiknock agent such as Tetraethyl lead is added. Now in lead free oils it is not used as it also harms catalytic converters.



10. Iron commonly have three forms, first form which is the crudest form is cast iron containing 2 to 5 percent carbon. Then there is steel which has 0.15 to 1.5% of carbon. Wrought iron is the purest form of iron having 0.12 to 0.25 percent of carbon.



11. On exposure to moist air, in the presence of carbon dioxide, iron is converted into brown hydrated iron oxide ( Fe2O3. 10 H2O). This process is called rusting.



12. Stainless steel contains 13% chromium.



13. Acids are generally sour, turn blue litmus red and generally give hydrogen with metals.



14. An acid is a substance which furnishes H+ ion on dissolving with water. It is proton donor and an electon acceptor.



15. Bases react with Acids to produce salt and water. They turn red litmus blue. They are also called alkalies eg. NaOH.



16. A base is defined as proton acceptor and an electron donor.



17. pH is negative logarithm of H ions. pH of neutral solutions is 7. For acidic solutions, pH is between 0 and 7 and for alkaline solutions it is between 7-14.



18. Metals occur in nature as chemical compounds called minerals. If these minerals are used as the starting material for extracting the metal, they are called ores.

Chemistry Notes for Prelims-2

Deliquescence and Efflorescence

* Solids like NaOH and Cacl2 become damp on exposure to moist air. Such substances are called deliquescent substances.

* On the other hand, crystals of washing soda loses a part of water of crystallisation (Na2CO3 . 10 H2O) and crumble into powder. Such substances are called efflorescent substances. 

FIRE EXTINGUISHERS 

Two methods of extinguishing a fire are:

a. Cutting off the supply of air.

b. Cooling the flames below the ignition temperature.

types:

Ordinary: Mixture of Water and CO2 

Foam Type: Fire covered by foam of oil and Sodium Bicarbonate.

Electrical Fires: Heavy Carbon Tetrachloride is put on fire.

COMBUSTION: It is the process of burning accompanied by the liberation of heat and light.

* It may take place in the presence of gases which support combustion eg.Oxygen or Chlorine.

* Farther the substance which burns must be raised to a particular temperature called ignition temperature.

EXPLOSION: It is sudden expansion of gases with a loud noise, owing to release of internal energy.

COMPOSITION OF AIR: Nitrogen: 78%, Oxygen: 21%, Argon: 0.9%

* Air is only a mixture and is not a compound.

* Oil contains unsaturated compounds. They add hydrogen and are converted into solid fats. This hydrogenation of oil is called 'vanaspati'.   

Peculiar Properties of Water: Even though molecular weight of water is low, it has unusually high boiling point. It is denser than ice.

Solid CO2 used in refrigerators is called dry ice.

Carbonic Acid  is also known as soda water.

Fuel is a substance that is used to produce heat energy.

Carbon Cycle: During day time , plants take up CO2 from air and return oxygen. At night the plants take in oxygen and gives out CO2. This cycle serves to maintain the % of  CO2 in air fairly constant.  

Gobar Gas: Obtained by fermentation of cow dung and water, inside a pit in the absence of air, also called 'biogas' used for running cooking, tubewells etc.

Aqua Regia: A mixture of Conc. HCl and conc. HNO3 in the ratio of 3:1 is called aqua regia. It can dissolve Gold and Platinum.

Laughing Gas: Nitrous Oxide: When inhaled, produce laughing. Used as anesthetic

General Biology Notes-2


Plants

Plants are divided into three parts:

1. Autotrophic

2. Heterotrophic

3. Insectivorous

Heterotrophic plants are divided into two parts Parasites- Which are totally dependent on living plants and animals and Saprophytes- Depend on dead and rotting organic remains of plants and animals.

Plants Micro Nutrients

1. N2 : Deficiency leads to decrease in angle between the stem and the leaf.

2. P: leads to abnormal color of leaf

3. Ca: Deficiency : Leaves appear abnormal in form or often show scorching or spotting effect.

4. Fe: Acute deficiency leads to scorching of leaf margins and tips. Mild deficiency leads to mottled patterns on leaf.

5. Mn: Deficiency leads to poorly developed root system.

6. Zn: In citrus plants, its deficiency causes mottled leaves.

7. Boron (B): Its deficiency leads to "Heart rot of suger beet and marigold"

Digestive, Teeth, Skeleton and Muscular System

Digestive System

The canal or body parts in which digestion takes place is called Alimentary Canal. It starts from mouth, and passing through Oesophagus (food pipe), stomach and small intestine finally ends into large intestine. Absorption of digested food mainly takes place in small intestines. Undigested and unabsorbed material then passes down the colon and rectum which absorb the excess water and with the help of putrefying bacteria form faeces. Finally the faeces passes out through the anus.

Human Digestive Enzymes

PartsDigestive Juice         Enzyme present
Mouth Saliva Ptylin
Stomach Gastric Juice Pepsin+ HCL, Renin, Gastric Lipose
Liver Bile Juice No Enzyme
Pancreas Pancreatic Juice Trypsin, Amylase, Pancreatic
Small Intestine    Succus Entericus Peptidases, Invertase, Lipase, Maltase, Lactase

- Digestion changes proteins into amino acids, carbohydrates into Monosaccharide glucose, fructose into galactose and fats into fatty acids and glycerols.

- Digestion of proteins is initiated in the stomach by the act of the enzyme pepsin.

- More than 50% of the energy content of the common diet comes from carbohydrates.

- For a normal person about 70 g of proteins and about 400-500 gms of carbohydrates are recommended.

Notes on General Chemistry-1

CHEMISTRY

SCOPE OF CHEMISTRY:

Deals with matter and the changes that matter undergoes when subjected to the action of heat light, electricity and other matter.
Elements: Substance which cannot be subdivided by any physical or chemical method.
Metals: Silver, Gold, copper sodium etc
Non metals: Oxygen, hydrogen sulphur etc.
Mixtures and compounds :
Iron + Sulphur = Mixture – Possesses both properties of iron and sulphur.
Iron + Sulphur-------------- Heated----FeS--- Compound- Properties of Iron and sulphur are lost.

Kinetic Theory of Matter: It says the pressure of a gas as due to bombardment of the wall of the vessel by the molecules of the gas.

Chemical Reactions:
Decomposition: (AB-------------- A+B)
Combination: (A + B--------------AB)
Double decomposition: (AB + CD----------- AD+ BC)
Displacement: (A +BC---------------- AC + B )

If the heat is evolved in a reaction it is called exothermic if heat is absorbed it is endothermic reaction.


ATOMIC STRUCTURE:
First given by John Dalton : says atom is indestructible.


Nucleas: Rutherford. The entire mass is concentrated in the nucleus which contain protons and neutrons, their total number equal to atomic mass.


The atomic number which is net positive charge on nucleus is equal to the number of protons.
Since the atom is electrically neutral , a number of electrons is equal to the number of the protons revolve around the nucleus.

Chemical Bonding: The force of attraction which binds the atoms in a molecule is called Chemical bonding.

Isotopes: They are atoms of the same element having the same atomic number but different atomic masses. They differ in the number of neutrons in the nucleus.

Nuclear fission: When certain heavy atoms like Uranium are bombarded with high velocity neutrons, new fast moving neutrons are released along with a large amount of energy. This process is called neuclear fission.

If all the neutrons are used in producing more fission a rapid and violent reaction takes place. This is the basis of the atomic bomb.


Nuclear Fusion: The two isotopes of hydrogen eg. Deutruim and Tririum react to produce, helium, neutron and a flood of energy. This is called fusion, and forms the basis of H-bomb.

Oxidation and Reduction:
Occur side by side.
Wherever there is oxidation, there is reduction.
When Chlorine oxidized Hydrogen sulphide to Sulphur, Hydrogen Sulphide reduces Chlorine to Hydrogen Chloride. Cl2 + H2S--------------- 2HCl + S

Oxidation: Removal of hydrogen or addition of oxygen or removal of electrons.
Reduction: Addition of hydrogen or removal or oxygen or addition of electrons.


Mathces: Side of the Box: Red phosphorous or phosphorous trisulphide.
Match Sticks: Impregnated with borax- so that they can be extinguished without glowing for a long time.


Heavy Water:
Discovered by Urey.
Contains heavy hydrogen atom i.e deuterium(D)
Formula D2O
Density 1.106

Used in Nuclear reactors to absorb neutrons

Notes on General Biology

NUTRITION AND DIET
The green plants and a few types of bacteria which are completely self supporting are called autotrophs.
This mode of nutrition in green plants is achieved mainly by the process of photosynthesis.
All animals including men and non-green plants show heterotrophic mode of nutrition.
Hetrotrophs obtain all their energy requirements mainly from organic substances like carbohydrates and fats.

FOOD
Energy yielding food:
Carbohydrates and fats
Body building food: Protein and Minerals
Protective food: Vitamins and minerals

Carbohydrates:
One Gram of carbohydrate provides 4.1 Cal.
Manufactured by green plants cia photosynthesis.
Lever converts carbohydrates into glycogen and stores in itself and muscles.
Gycogen is known as animal starch as it is not produced in plants.
Excess carbohydrates is converted to fats.

Fats:
One gram of fat provides 9.3 calories of energy.
Stored as future foods.

Proteins
There are made of amino acids which are the only source of nitrogen in the body.
Amino Acids were discovered by William Rash of USA
One gram of protein provides 4.1 calories.
Proteins are raw material for manufacturing of Hormones, enzymes, antibodies etc.

Minerals:
Vitamins and Minerals are called micronutrients while protein, carbohydrates and fats are called macronutrients.
Ca and P form about ¾ of minerals.
Phosphorous: Metabolism
K and Mg: Muscle Contraction
Na and K: Propagation of nerve impulse and for water balance of the body.
Iron: Raw material for RBC
Iodine: thyroid Glands functioning

Mineral Deficiency Diseases
Anemia: Iron deficiency
Rickets : Calcium
Goiter: Deficiency of Iodine.

Water:
An average man contains about 45 litre of water which is 70% of body weight.

Vitamin:
Funk for the first time used the word Vitamin.
Vitamin A, D, E, K:- Fat soluble
Vitamin B and C:- Water soluble

Vitamin (A) (Retinol) :
Sources: Cod lever oil, egg yolk, yellow vegetables.
Deficiency symptoms: Night Blindness, Xerophthalmia.

Vitamin (B) ( Thiamine):
Sources
: Grains, meats, green vegetable.
Deficiency symptoms: Beriberi

Notes on Fundamental Rights

Fundamental Rights
Part III of the Indian Constitution( A 12-35) deals with the FR granted to individuals.
Originally seven groups of rights. But now 44th Amendment ‘Right to property’ deleted.
1) Right to equality and liberty : Art (14-18)
14: Equality before law
15: Prohibition of discrimination
16: Equality of opportunity
17: Abolishes practices of untouchability
18: Prohibits state from confirming any title

2) Right to Freedom. (19-22)
-Freedom of speech and expression
-Freedom of Assembly
-Freedom to form associations
-Freedom to move freely throughout India
-Freedom to reside and settle in any part of the country
-Freedom to practice any profession

3) Right against Exploitation (23-24)
Art 23: Prohibits traffic against human beings and beggar
Art 24: Prohibits employment of children below 14 years of age in factories mines etc.

4) Right of Freedom of Religion (25-28)

5) Right for Culture and Education (Article 29-30)

6) Right to Constitutional Remedies(Article 32)

• Dr Ambedkar call article 32 as “the very soul of the constitution and the very heart of it”.

• In Golaknath case in 1967, the SC ruled that parliament has no power to amend any of the provisions of part III so as to take away or abridge fundamental rights as guaranteed by the constitution.

• In Keshawnand Bharti case, the SC ruled that parliament has power to amend, but it can not destroy the basic structure of the constitution.

• In T.K,Rangarajan Vs Govt of TN and others, SC observed that govt employees including doctors working in state run hospitals and dispensaries have no “fundamental, legal, moral or equitable right to go on strike even for a just cause".

Distinction between Fundamental Rights and Directive Principles
