litmus paper. because it

Answer 2

Answer:

a) ➡ 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 ) ➡ 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 .
