Salt of strong acid and strong base, e.g. Naci. 2. Salt of strong acid and weak base, e.g. NH4CI. 3. Salt of weak acid and strong base, e.g. NaAc. 4. Salt of weak acid and weak base, e.g. NH4Ac.

Answer 1

Voltaren Gel    diclofenac sodium salt        benzoicacid salt                   Ka =10-4 , Ca=.001 M H+ = (10-4 *10-3)1/2

                                                                 (weak acid strong base)                         pH =3.5
