Answer
This salt is acidic.
Work Step by Step
1. Analyze each type of ion in this salt, and determine which is stronger:
- $Fe^{3+}$: Lewis acid (Weak acid).
Most transtion metal cations are Lewis acids.
- $Cl^-$
- Strong acids have insignificant bases as conjugate pair.
- $Cl^-$ is the conjugate base of $HCl$, which is a strong acid.
- $Cl^-$: Insignificant base.
Therefore: the stronger ion is $Fe^{3+}$, and since it is an acid, this salt is acidic.
