Question

On basis of strength That is concentration of OH ions ,state strong and weak alkali

Answer 1

A strong alkali is one which has high OH- concentration.

In a strong alkali there is high dissociation to produce more OH-

An example of a strong alkali is NaOH. When dissolved in water, it dissociates fully to give Na+ and OH-



A weak alkali is one which has low OH- concentration.

In a weak alkali there is partial dissociation to produce few OH-

An example of a weak alkali is NH4OH. When dissolved in water, it dissociates partially to give NH4+ and OH-
