What effect does the presence of dissolved sodium fluoride have on the dissociation equilibrium of hydrofluoric acid? (select all three that apply) ...
The percent dissociation of HF is reduced by the presence of dissolved NaF.
THe pH of the solution containing NaF and HF would be higher than that of a solution of HF only.
The presence of NaF drives the reaction towards the HF side to reach equilibrium.
The concentration of H + is higher in an HF solution containing NaF.
The pH of the solution containing NaF and HF would be lower than that of a solution of HF only.
The presence of the dissolved NaF does not affect the HF equilibrium reaction nor the equilibrium concentrations.
