Question

write few applications of acid and bases

Answer 1

Acid is a substance that produces hydrogen ions (H+) in water solution. (1) The ability to produce theses ions give acid their unique property that they have. (1) It is also a substance that have a PH less than 7 when it is seven that mean it is neutral .(2) A PH scale is a scale that show acidic or basic a solution is. (2) .The more a substance is acidic then that means the lower its PH is. (2) for example we have lemon juice that have citric acid and ascorbic acid which is vitamin C, lemon have a PH of two which mean it is acidic. (2) There is an organic substance that is called indicator that changes color when it touches an acid or a base. (1) An example of this organic substance is blue litmus paper that turns red in acid. (1) There are many types of acids like hydrochloric acid, nitric acid, phosphoric acid, sulfuric acid, etc. When some acid is intact with metal it sometimes react strongly which eat it away as metallic compound and hydrogen gas form, acids also donate H+ and its solution can transfer/move electricity. Also is have a sour taste and when it react with base it give us salt and water. Give sharp stinging pain when put on a cut or wound. 

Bases are a substance that produces hydroxide ions when it dissolves in water.  It is considered any substance that accepts (H+) from acids. When acids donate H+ the one to take them is bases in other world both are complement to each other.  Of course that is not all; bases have a lot of property. For example it feel slippery this feeling is caused because when it touch your skin it to dissolve a little bit, taste bitter, react with oils and greases, and it is frequently solids.When the PH is above seven that mean that it is a base. It also cause red litmus indicator to turn blue and its solution can transfer electricity. There are a lot of types of bases like aluminum hydroxide, calcium hydroxide, ammonia, etc.
