Chapter 13: Problem 82
Calculate the van't Hoff factors of the following weak electrolyte solutions: (a) \(0.050 \mathrm{m}\) HCHO \(_{2}\), which begins to freeze at \(-0.0986^{\circ} \mathrm{C}\).(b) \(0.100 \mathrm{M} \mathrm{HNO}_{2},\) which has a hydrogen ion (and nitrite ion) concentration of \(6.91 \times 10^{-3} \mathrm{M}\).
