Problem

Hydrofluoric acid, HF(aq), is a weak electrolyte. A solution of HF is titrated with aqueous NaOH. Which of the following is the correct net ionic equation for the reaction occurring during the titration? (a) HF(aq)+OH−(aq)→F−(aq)+H2O(l)\mathrm{HF(aq) + OH^- (aq) \rightarrow F^- (aq) + H_2O(l)} (b) H+(aq)+OH−(aq)→H2O(l)\mathrm{H^+ (aq) + OH^- (aq) \rightarrow H_2O(l)} (c) HF(aq)+Na+(aq)+OH−(aq)→NaF(aq)+H2O(l)\mathrm{HF(aq)+ Na^+ (aq) + OH^- (aq) \rightarrow NaF(aq)+ H_2O(l)} (d) F−(aq)+H+(aq)→HF(aq)\mathrm{F^- (aq) + H^+ (aq) \rightarrow HF(aq)}
