The pH of an $KCH_3COO$ solution will be greater than 7. This happens because, this salt is formed by an insignificant acid $(K^+)$ and a weak base $(CH_3COO^-)$, therefore, the solution is basic.
Work Step by Step
To predict the pH range of an salt: 1. Identify the ions that form this salt, and compare their strengths: 1 $K^+$: Conjugate acid of a strong base $(KOH)$: Insignificant acid. 1 $CH_3COO^-$: Weak base. Therefore: $CH_3COO^-$ is the stronger electrolyte, so, the solution is basic.
