sulfurous acid ($h_2so_3$) is a polyprotic acid. write balanced chemical equations for the sequence of reactions that sulfurous acid can undergo when its dissolved in water.

sulfurous acid ($h_2so_3$) is a polyprotic acid. write balanced chemical equations for the sequence of reactions that sulfurous acid can undergo when its dissolved in water.

Answer

Explanation:

Step1: First - dissociation step

$H_2SO_3(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+HSO_3^-(aq)$

Step2: Second - dissociation step

$HSO_3^-(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+SO_3^{2 - }(aq)$

Answer:

$H_2SO_3(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+HSO_3^-(aq)$ $HSO_3^-(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+SO_3^{2 - }(aq)$
