Question

Equivalent weight of $S{O}_2$ is found to be 32 in a reaction taking place in acidic medium. This reaction is represented as $S{O}_2+2H_{2}O\to S{O}_4^{2-}+4H^{+}+2e^{-}$

State whether the given reaction take place in backward direction or forward direction?

Answer 1

In acidic medium,

$S{O}_4^{2-}+4H^{+}+2e^{-}⟶S{O}_2+2H_{2}O$

This reaction is take place in forward,not in backward direction.
