predict if the solutions of the following salts are neutral, acidic or basic : NaCl, KBr, NaCN, NH4NO3, NaNO2 and KF. 

Answer

(i) NH4NO3 solution is acidic, as it is a salt of the strong acid and a weak base, having pH < 7.
(ii) NaCN, NaNO2, KF solutions are basic, as they are salts of a strong base and a weak acid, having pH > 7.
(iii) NaCl, KBr solutions are neutral, as they are the salts of a strong acid and strong base, having pH = 7.
