CUET Chemistry Chemistry in Everyday Life: Important Points to Remember

There are following important points in this chapter of Chemistry in Everyday Life.

CUET Chemistry: Drug & Medicine

The Drug:

It is a chemical substance used in the treatment, cure, prevention and diagnosis of diseases.

Medicine:

The drugs which are therapeutic and used for diagnosis, prevention and treatment of diseases.

Antiseptics:

Chemicals which kill or prevent the growth of microorganisms, and are harmless to human living tissues. They are applied to wounds, cuts, ulcers, diseased skin surface. Example: Dettol (mixture of chloroxylenol and terpenol).

Disinfectants:

Chemicals which kill or prevent the growth of microorganisms but are toxic to human living tissues. They are used to disinfect inanimate objects. Examples: Floors, instruments.

Narrow spectrum Antibiotic:

Antibiotics which are effective mainly against Gram – positive or Gram – negative bacteria are called narrow spectrum antibiotics. Examples: eg: penicillin – Ampcillin and Amoxycillin. 

Broad spectrum Antiboitics:

Antibiotics which kill or inhibit a wide range of Gram – positive & Gram negative bacteria are called broad spectrum antibiotics. Examples: Tetracycline, chloramphenicol, vancomycin, ofloxacin.

Artificial Sweetening Agents:

CUET Chemistry: Soaps and Detergent

Soaps containing sodium salts are formed by heating fat (i.e., glyceryl ester of fatty acid) with aqueous sodium hydroxide
solution. This reaction is known as saponification. 

Anionic Detergents:

Cationic Detergents:

Cationic detergents are quaternary ammonium salts of amines with acetates, chlorides or bromides as anions.

Cationic part possess a long hydrocarbon chain and a positive charge on nitrogen atom.  

Non-ionic Detergents:

The branching of the hydrocarbon chain is controlled and kept to the minimum because unbranched chains can be biodegraded more easily and hence pollution is prevented.

CUET Chemistry: Important Points

Tincture of iodine (alcohol – water solution containing 2 – 3 % iodine) is a powerful antiseptics.

Barbiturates are hypnotic, i.e., sleep producing agents.

Chlorine in the concentration of 0.2 to 0.4 ppm in aqueous solution and sulphur dioxide in very low concentrations, are
disinfectants.

Boric acid in dilute aqueous solution is weak antiseptic for eyes.
