Answer
The pH at the equivalence point is equal to 7.
Work Step by Step
- Write the reaction:
$Ca(OH)_2(aq) + HClO_4(aq) -- \gt Ca^{2+}(aq) + Cl{O_4}^-(aq) + H_2O(l)$.
- Analyzing the remaining compounds.
$Ca^{2+}:$ Insignificant acid.
$Cl{O_4}^-:$ Insignificant base.
Therefore, there are no significant electrolytes remaining in the solution:
Neutral pH:
$pH = 7$
