Answer 2

Answer:

Ammonia when dissolved in water it forms ammonium hydroxide.

Ammonium hydroxide readily ionizes to form ammonium ions (NH4+) and hydroxide ions (OH-). Thus the solution ammonia is considered as a base.

When ammonia dissolves in water it is believed that the ammonia accepts a hydrogen from the water due to the lone pair of electrons of the nitrogen in ammonia, this leaves an hydroxide ion that allows the solution to be basic.

A base is a proton acceptor. On the pH scale, bases have a pH greater than 7. Ammonia (NH 3 ) is a base because it can accept protons from water (H20) forming negatively charged hydroxide ions (OH-).

NH3(aq) + H2O(l) --> NH4+(aq) + OH-(aq)
