Question

$H_{2}S{O}_4$ is a stronger acid than $H_{2}S{O}_3$.
If true enter 1, else enter 0.

Answer 1

$H_{2}S{O}_4$ is a stronger acid than $H_{2}S{O}_3$.

The oxidation state of S is more in $H_{2}S{O}_4$ which is $+7$ as compared to $+4$ in $H_{2}S{O}_3$.
Greater is the oxidation state of central atom, the more it attracts the electrons towards itself and also, more it stabilises the conjugate base.

Therefore, $H_{2}S{O}_4$ is a stronger acid.
