A salt of strong acid and strong base does not undergo hydrolysis. Explain.OR An aqueous solution of sodium chloride is neutral. Explain.

Answer»

(1) Sodium chloride is a salt of strong acid HCl and strong base NaOH.

(2) In water, it reacts forming HCl and NaOH.

(3) As both are strong, they dissociate almost completely to liberate H+ and OH- ions, respectively.

(4) H+ and OH- ions combine together to form weakly dissociating H2O. As there are no free H+ ions and OH- ions, the solution is neutral and the salt does not undergo hydrolysis.

NaCl + H2O ⇌ NaOH + HCl

Ionic equation :

Na+ + Cl- +H2O ⇌ Na+ + OH- + H+ + Cl-

H2O ⇌ H+ + OH-

Since the solution contains equal number of H+ and OH- ions, it is neutral.

Hence the salt of strong acid and strong base does not undergo hydrolysis.
