In its natural form, salt does not have a pH balance. A pH balance is only used with solutions that are liquid based. The term pH refers to the hydrogen levels in a solution, which is what affects a solution's acidic/alkaline levels.
Due to the varying structures of salts, they can influence the pH balance of the water in a number of different ways when added to a solution. Salts that are derived from weak bases and strong acids, for example, give the solution a pH balance of less than 7. Alternatively, when the salt comes from strong bases and weak acids, it can increase the pH balance to above 7.
