Answer:
Ammonia (NH3) is considered a weak base because it does not completely dissociate into ions when dissolved in a solvent.
Explanation:
Take this reaction for example:
NH3 + H2O --> NH4+ + OH-
Ammonia is considered a base because it can accept a proton from water (in the form of H+).
If you draw a Lewis Dot Structure, you can see that the nitrogen in NH3 has a lone pair of electrons. Ammonia is also considered a base because it donates these electrons to one hydrogen from water (H+), forming a positive ion (NH4+) and leaving water as a negative hydroxyl ion (OH-).
It is consider a weak base because when this reaction occurs, NH3 does not completely dissociate into NH4+ and OH- ions.

When react with water its become NH4 + OH- and base give OH- when react with water
