Answers

The freezing point of $0.109 \mathrm{~m}$ aqueous formic acid is $-0.210^{\circ} \mathrm{C}$. Formic acid, $\mathrm{HCHO}_{2}$, is partially dissociated according to the equation $$ \mathrm{HCHO}_{2}(a q) \rightleftharpoons \mathrm{H}^{+}(a q)+\mathrm{CHO}_{2}^{-}(a q) $$ Calculate the percentage of $\mathrm{HCHO}_{2}$ molecules that are dissociated, assuming the equation for the freezing-point depression holds for the total concentration of molecules and ions in the solution.
