Strong Base 

Weak Base

They get completely ionized (split up into ions)  in water and produce large amounts of hydroxide ions.

These only get partially ionized (split up into ions) in water and produce less amount of hydroxide ions.

pH value is close to 14 but smaller than it.

pH value is closer to 7 but greater than it.

These are highly reactive
