Salts of strong acid and strong base do not hydrolyse and form a neutral solution, thus, pH will be nearly 7 of KNO3. In sodium acetate, acetic acid remains unionised. This results in an increase in OH- concentration and pH will be more than 7. NH4Cl formed from a weak base, NH4OH and strong acid, HCl, in water dissociate completely, aq. ammonium ions undergo hydrolysis with water to form NH4OH and H+ ions resulting in less pH value.
