Chapter 22, Problem 27R

To determine

To Compare:Weak Base-Strong base

Explanation of Solution

A base, which dissociates almost completely in the water at ordinary dilution, thus producing a large number of ${\text{OH}}^{-}$ ions is called a strong base.

A base that dissociates to a small extent in the water at ordinary dilution to give a low concentration of ${\text{OH}}^{-}$ ions is called a weak base.

Conclusion:

A strong base dissociates completely in water producing a large number of ${\text{OH}}^{-}$ ions, while a weak base dissociates to a small extent in the water at ordinary dilution, producing a low concentration of ${\text{OH}}^{-}$ ions.
