Question

Give reasons : 2M

a) Solution of sulphuric acid conducts electricity whereas alcohol does not.

b) Dry ammonia gas has no action on litmus paper but a solution of ammonia in water turns red

litmus paper.​

Answer 1

Explanation:

a)answer = Because sulphuric acid is a strong electrolyte.it can break down in free mobile ions which can conduct electricity but alcohol is non electrolyte it cant be break down in ions to conduct electricity.

b)answer = Dry Ammonia gas has no action on litmus paper but a solution of ammonia in water turns red litmus blue . This is because , in the absence of water it cannot split apart or dissociate into ions . ➡Hence it forms ammonium Hydroxide ( NH4OH) this is basic in nature . Hence it turns blue litmus red .
