Solution: Why can we ignore the contribution of water to the concentration of OH − in a solution of the following bases:0.0784 M C6H5NH2, a weak base0.11 M (CH3)3N, a weak basebut not the contribution of water

Problem

Why can we ignore the contribution of water to the concentration of OH in a solution of the following bases:

0.0784 M C6H5NH2, a weak base
0.11 M (CH3)3N, a weak base
but not the contribution of water to the concentration of H 3O+?
