Question

Ammonia is a base but does not hydroxyl ions . Why ??

Answer 1

Hulloa friend!!
Rajdeep here...

Ammonia is an alkaline gas, but it does not have hydroxyl ions. Hydroxyl ions are the ions with a coordinate bond. They are formed ONLY WHEN AN ALKALINE SUBSTANCE IS DISSOLVED IN WATER. Due to the dielectric constant power of water, the ions of a polar covalent compound like ammonia is split.

NH3 + H2O ----> NH4OH
NH4OH -----> NH4+    +    OH-

Thus, when ammonia is dissolved in water and we get ammonia solution (ammonium hydroxide), we get hydroxyl ions there. 

Thanks!!

Answer 2

Answer:

Hey here is your answer.....

Ammonia when dissolved in water it forms ammonium hydroxide.

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