Long Answer TypeDiscuss the salt hydrolysis in the following cases:
(i) Salts of strong acid and strong base
(ii) Salts of strong acid and weak base
(iii) Salts of weak acid and strong base
(iv) Salts of weak acid and weak base.
Short Answer Type(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.
Long Answer TypeDerive the relation,
in the case of hydrolysis of salts of strong acids and weak acids.
Show that for an aqueous solution of a salt of weak base and strong acid 
where 
is the degree of hydrolysis.
