We have created solutions to various NCERT exemplar solutions in a unique and simple manner. By following these Solutions, you may boost your marks in CBSE Board exams.

Important Topics for NCERT Exemplar Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life

  1. Medicines or Drugs: A chemical that can be used to treat a disease or reduce pain is called a drug or drug.
  2. The area of science that uses chemicals to treat diseases [therapeutic effects] is called chemotherapy.
  3. Some important classes of drugs are:
  • Antacid:  Drug that neutralizes excess acid in gastric juice and raises the pH to an appropriate level in the stomach. Milk is a weak antacid.
  • Tranquillizers (psychotherapeutics): Chemicals used to treat stress, anxiety, hypersensitivity, mild or severe mental illness are known as tranquillizers.
  • Non-adrenaline: It is one of the neurotransmitters that play a role in mood changes. With low levels of noradrenaline, signalling activity is diminished, and a person can suffer from depression. 
  • Barbituric acid: Barbiturates are hypnotics or sleep-generating agents.
  • Equanil is used to control depression and high blood pressure.
  • Analgesics Medicines: It is used to relieve pain and is called pain relievers. 
  1. They are of two types:
  • Narcotics Drugs: The drugs that cause sleep and loss of consciousness are called drugs. These are addictive drugs. For example, morphine and codeine. Morphine diacetate is commonly known as heroin. 
  • Non-Narcotics: These are non-addictive chemicals that reduce mild to moderate pain like headache, toothache, muscle, and joint pain, etc. They are also called non-addictive. 
  • Antipyretic: They are chemical substances that reduce body temperature during high fever. 
  • Antimicrobials: Antimicrobials tend to kill or prevent the growth of microbes, which selectively inhibit the pathogenic effects of microbes, such as bacteria, fungi, and viruses.
  1. Antimicrobial drugs are as follows :
  • Antibiotics: These are substances that can kill microorganisms in low concentration or interfere with their metabolic processes (manufactured in whole or in part by chemical synthesis). 
  • There are two types of antibiotics: 
  1. Antibiotics: They have a saddle effect on microorganisms. For example, penicillin, ofloxacin, aminoglycosides, etc. 
  2.  Antiseptic: These are chemicals that kill and stop growth germs.

 

  1. Some prominent examples of antiseptics :
  1. Dettol is a mixture of chloroxylenol and terpineol. 
  2. Soap is added to the Vessel to reduce the odour generated by bacterial organic substances in the skin and has an antioxidant effect. 
  3. Iodine tincture alcohol contains a 2-3% solution of iodine, which is a powerful preservative for injuries. 
  4. Iodoform (CHI3) is used as a wound disinfectant. 

 

  1. Disinfectant: A chemical that kills microorganisms that are not safe for use in living tissue.
  1. 8.   Chemicals in food
  2. Artificial sweeteners: Sucrose (table sugar) and fructose are the most widely used natural sweeteners. But they contribute to our calorie intake and promote tooth decay
  3. Food preservatives: These are chemicals that are added to foods to prevent the growth of microbes (bacteria, yeast, and mould) and to maintain nutritional value for a long time.
  4. Disadvantages of soap
  5. Soap is not used in hard water. 
  6. Soaps are not used in acid solutions because acids contain insoluble free fatty acids.
  7. Soap / Soap Synthetic Cleanser: Synthetic detergents have all the properties of soap, but are called soaps.
  8. d. Detergents are found in three main types:
  9.   Anionic detergents: These are sodium salts of Long Chain sulfonated alcohol or hydrocarbons. 
  10. Cationic detergents: These are quaternary aluminium salts containing anyone, chloride or bromide ion. 
  11. c. Non-antimicrobial detergent: These soaps do not contain ions. 
  12. Advantages of synthetic detergent over soap: 
  13. Synthetic detergent can also be used in solid water, but soap does not. 
  14. Synthetic detergents can be used in acidic nature, hence making a better tooth than soap.
  15. Synthetic detergents are highly water-soluble.
  16. Artificial detergent has a much cleansing effect than soap.
