Question
8.71ml of a 4.00M HIO3(aq) solution is added to an ice-water mixture, and the freezing points were collected before and after
addition of HIO3(aq). Once the temperature was stable after addition, the ice was separated from the solution and the mass of the
beaker with solution was measured. The data below was recorded. Calculate the van't Hoff factor for HIO3. The freezing point
depression constant for water is 1.86°C/m.
