there are 4 properties of salt
1. The salt of a strong acid and a strong base is neutral
2. The salt of a strong acid and a weak base is acidic
3. The salt of a weak acid and a strong base is basic
4. Salt of a weak acid and a weak base depends on the value of the ionization constant of the acid and base
So the salt from strong acid + weak base is acidic
and salts of strong acids and weak bases (pH<7) or of strong bases and weak acids (pH>7) will be partially hydrolyzed
