Question

Both $H_{2}S{O}_3$ and $H_{2}S{O}_4$ are dibasic acid. But, equimolar solutions of both acids do not contain equal concentration of $H^{+}$ ions. Give reason.

Answer 1

Equimolar solutions of $H_{2}S{O}_3$ and $H_{2}S{O}_4$ do not contain equal concentration of $H^{+}$ ions because the dissociation constant of $H_{2}S{O}_4$ is generally higher compared to many acids.
