Answer:
1.) Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. For example, every time you digest food, acids and bases are at work in your digestive system.
2.) Definition. A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.
3.) common uses of acids - Sulphuric acid is used in car batteries. It is used in the manufacture of paints, drugs, dyes, and to produce fertilizers.
acid uses:
•Citric acid — As a preservative for food As a flavouring agent
•Ascorbic acid (also called vitamin C) — In the treatment of bone marrow and scurvy diseases
bases uses:
•Sodium hydroxide— In the manuacture of soaps, textile, paper, medicines In the refining of petroleum
•Ammonium hydroxide— As a reagent in the laboratory In making fertilizers, rayon, plastics and dyes
4.)Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity.Cells secrete acids and bases to maintain the proper pH for enzymes to work . The enzyme pepsin, which helps break down proteins in the stomach can only function optimally in the low pH environment.
