How do cations and anions in a salt influence the acidity or neutrality of a solution?

Anions determine the acidity while cations determine the basicity of the solution.

Neither cations nor anions have any effect on the acidity or neutrality of a solution.

Only cations influence the acidity or neutrality, regardless of anion behavior.

Both cations and anions influence the acidity or neutrality by their inherent charge and ability to dissociate into H+ or OH-.
