The $K_a$ values for $\mathrm{HPO}_4^{2-}$ and $\mathrm{HSO}_3^{-}$are $4.8 imes 10^{-13}$ and $6.

Question

The $K_a$ values for $\mathrm{HPO}_4^{2-}$ and $\mathrm{HSO}_3^{-}$are $4.8 	imes 10^{-13}$ and $6.3 	imes 10^{-8}$ respectively. Therefore, it follows the $\mathrm{HPO}_4^{2-}$ is a $\_\_\_\_$ acid than $\mathrm{HSO}_3^{-}$and $\mathrm{PO}_4^{3-}$ is a $\_\_\_\_$ base than $\mathrm{SO}_3^{2-}$.
