4.What will be the freezing point of aqueous 0.1m KCl. soln, if Kf for 2 86.1OH K.Kg.mol. (a) C186.0 (b) C372.0 (c) C86.1 (d) C
Question
Solution 1
The freezing point depression, ΔTf, is calculated using the formula:
ΔTf = i * Kf * m
where: i is the van 't Hoff factor, which is the number of ions the compound dissociates into in solution. For KCl, this is 2 (K+ and Cl-). Kf is the cryoscopic constant of the solvent (water in this case), which Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
