Answer
This solution is "pH-neutral".
Work Step by Step
1. Analyze each type of ion in this salt, and determine which is stronger:
- $Ca^{2+}$
- Strong bases have insignificant acids as conjugate pair.
- $Ca^{2+}$ is the conjugate acid of $Ca(OH)_2$, which is a strong base.
- $Ca^{2+}$: Insignificant acid.
- $Br^-$
- Strong acids have insignificant bases as conjugate pair.
- $Br^-$ is the conjugate base of $HBr$, which is a strong acid.
- $Br^-$: Insignificant base.
There isn't any significant electrolyte, so, this salt is neutral.
