The experimentally measured freezing point of a 1.25 m aqueous solution of AlCl3 is -7.44°C. The freezing point depression constant for water is Kf = 1.86°C/m. Assume the freezing point of pure water is 0.00°C.
A.) What is the value of the van't Hoff factor for this solution?
B.) What is the predicted freezing point if there were no ion clustering in the solution? In degrees Celsius
