Acid base titration

A salt formed between a strong acid and a weak base is an acid salt, for example NH4Cl.

• A salt formed between a strong acid and a weak base is an acid salt, for example NH4Cl.
• A salt formed between a weak acid and a strong base is a basic salt, for example CH3COONa.
• These salts are acidic or basic due to their acidic or basic ions as shown in the tables here.
