An aqueous solution of formic acid, that is 1.00 percent by weight formic acid, has a density of 1.0006 g/mL. A student determines that the freezing point of this solution is -0.418 °C. Based on the observed freezing point, what is the percent ionization of the acid and the value of Ka? Kf for H2O is 1.86 °C/m.
