The salt of a STRONG ACID and a weak base is acidic. (The strong reactant "wins out", so the solution is ACIDIC.) Alternatively, a reaction between a STRONG ACID and a weak base produces spectator ions plus a weak conjugate acid at the equivalence point, and therefore will be ACIDIC.

A STRONG ACID and a weak base requires an indicator which changes color in the range pH = 4-6.

Titrating a weak base with a STRONG ACID results in  pH < 7 at equivalence point.
