Answer
This salt will be basic.
Work Step by Step
1. Analyze each type of ion in this salt, and determine which is stronger:
- $K^{+}$
- Strong bases have insignificant acids as conjugate pair.
- $K^+$ is the conjugate acid of $KOH$, which is a strong base.
- $K^+$: Insignificant acid.
- ${CO_3}^{2-}$
- Weak acids have weak bases as conjugate pair.
- $C{O_3}^{2-}$ is the conjugate base of $HC{O_3}^-$, which is a weak acid.
- ${CO_3}^{2-}$ is a weak base.
Therefore: the stronger ion is ${CO_3}^{2-}$, and since it is a base, this salt is basic.
