Answer

The aqueous solution of this compound will be neutral.

Work Step by Step

1. Identify the ions present in the salt: - ($K^+$) - ($C{lO_4}^-$) 2. Compare, and determine which one is stronger: - $K^+$ is the conjugate acid of a strong base (KOH), therefore, it has negligible acidity. - $Cl{O_4}^-$ is the conjugate base of a strong acid ($HClO_4$), therefore, it has negligible acidity. So, since none of the ions will react significantly, the solution will be neutral.
