Answer
A $Na_2SO_3$ solution will be basic.
Work Step by Step
1. Identify the strength of each ion in the salt:
$Na^+$: Insignificant acidity.
- Since $Na^+$ is the conjugate acid of a strong base $NaOH$, it has a negligible acidity.
$S{O_3}^{2-}$: Weak basicity:
- Since $S{O_3}^{2-}$ is the conjugate base of a weak acid: $HS{O_3}^{-}$, it has a weak basicity.
Therefore, since the stronger ion is a base, the solution will be basic.
