Salts that are from strong bases and weak acids do hydrolyze giving it the pH greater than 7. The anion in the salt is derived from a weak acid, most likely organic, and will accept the proton from the water in the reaction having the water act as an acid in this case leaving a hydroxide ion (OH-). The cation will be from a strong base, meaning from either the alkaline or alkaline earth metals so like before it will dissociate into an ion and not affect the H+.
Salts producing a basic pH are salts of weak acids and strong bases. These salts have a neutral cation and a basic anion. For example, NaF dissociates into Na+ and F– ions. The Na+ ion has no acidic or basic properties, but the fluoride ion is a conjugate base of a weak acid and therefore is a basic anion.
NaF a salt of the NaOH, a strong base, and HF, a weak acid.
