Question

Assertion (A) : A solution of NH3 in water turns blue litmus red.

Reason (R) : In water, ammonia forms NH4OH which dissociates to give NH4

+ and OH– ions​

Answer 1

Explanation:

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 .
