First, dissociate the salt into ions:
NaF(aq) → Na+(aq) + F–(aq)
Check the cation for hydrolysis:
Na+(aq) + 2 H2O(l) NR NaOH(aq) + H3O+(aq)
No, the reaction does not occur because NaOH is a strong base.
Check the anion for hydrolysis:
F–(aq) + H2O(l) → ← HF(aq) + OH–(aq)
This reaction does occur because HF is a weak acid.
