• There are many instances in your everyday life that involve the knowledge of chemistry, its applications, and its rules. 

                                           

Chemistry play crucial role. some of these are:

  • Chemical fertilizers such as calcium superphosphate, urea, ammonium sulfate, and sodium nitrate. These chemicals have assisted greatly in increasing the yield of fruits, vegetables, and other crops 

                         

  • Manufacture of pesticides, but depending on the targeted pest, pesticides include fungicides, herbicides, and insecticides. 

                               

  • Manufacturing of better quality plastic pipes for irrigation, and it is commonly used in farming. 

                                     

  • Other than agricultural products, chemistry has led to the discovery of different kinds of food preservatives.

  • Consumers have benefited from new technologies that have increased their food availability, appearance, nutritional content, and flavor. 

                                   

  • A local example of food processing and keeping it for a longer period of time is the preservation of raw meat.

                         

  • Chemistry has provided mankind with a large number of life-saving medicines.
  • We could find a cure for dysentery and pneumonia as a result of the discovery of sulfur drugs and penicillin.
  • Besides this, life-saving drugs like cisplatin and Taxol are effective for cancer therapy, and AZT is used for AIDS victims.

1. Disinfectants    

2. Analgesics    

3. Anesthetics     

4. Antibiotics  

5. Antiseptics  

6. Tranquilizers

1. Disinfectants

  • Are used to kill the microbe present in toilets, floors, and drains. The sanitizers we use for Covid-19 belong to this group. 

                                       

2. Analgesics

  • An analgesic, or painkiller, is any member of the group of drugs used to achieve analgesia, relief from pain. 

                                   

3. Anesthetics

  • Has made medical operations more and more effective via relieving pain. 

                                         

4. Antibiotics

  • Are used to control infection and cure diseases. 

                               

5. Antiseptics

  • Are used to contamination of the wounds by bacteria. 

                                           

6. Tranquilizers

  • To reduce tension and bring about calm and peace to patients suffering from mental diseases. 

                                       

  • Providing building resources such as glass, steel, and cement, chemistry helps in the construction of safer houses and multi-story structures.

  • It also helps in the construction of long-lasting and durable dams and bridges. 

                     

 

1. List down the role of chemistry in your locality.

2. What problems, do you think, will be observed in the livelihood of the community in which you are living in the absence of enough knowledge of chemistry? 

  • Human life would be full of problems and challenges.

  • Different diseases, especially diseases like HIV, AIDS, etc., would have killed more than we can imagine.

  • The problem  of air and water pollution would have been rampant.

  • In general, life would have been much more challenging than it is today.

3. In your opinion, what further roles can chemistry play? 

  • By using the knowledge of chemistry,

  • Different problem can be  solved

For examples

  •   Water pollution, air pollution and soil pollution
