What pH do salts have?

Well they could be neutral..........


Sodium hydroxide and hydrochloric acid react to form sodium chloride and water. The salt, sodium chloride, does not undergo hydrolysis in aqueous solution.

On the other hand, some salts, for instance sodium fluoride, the salt of a weak acid, and a strong base, gives rise to a slightly basic aqueous solution:

#NaF(s) + H_2O(l) rightleftharpoons NaOH(aq) + HF(aq)#

Anyway, the acidity/basicity of any salt in aqueous solution must be established by measurement.
