Protonation is the process of receiving a H+ ion, just as a base may receive a proton. I think this is why percent ionization is for acids and percent protonation is for bases. WebbThe base will accept a proton from water and form a conjugate acid, BH + . This equilibrium has its own special constant, K b, known as the base dissociation constant. Like the acid dissociation constant, it is defined as the equilibrium constant multiplied by the concentration of water. Ion Product Constant [ edit edit source]
