Chemistry 112

First, dissociate the salt into ions:

ZnF2(aq) → Zn2+(aq) + 2 F(aq)

Check the cation for hydrolysis:

Zn2+(aq) + 2 H2O(l) ZnOH+(aq) + H3O+(aq)

Yes, the reaction does occur because ZnOH+ is a weak base.

Check the anion for hydrolysis:

F(aq) + H2O(l) HF(aq) + OH(aq)

This reaction does occur because HF is a weak acid.
