SUMMARY
This discussion focuses on calculating the freezing and boiling points of solutions using the van't Hoff factor and the formula ΔT = imK. For the 0.070 m MgCl2 solution, the van't Hoff factor (i) is 3, while for the 0.020 m FeCl3 solution, it is 4. The change in temperature (ΔT) can be determined once the specific K values for the solvents are obtained from reliable sources such as textbooks or online databases. The calculations require knowledge of the freezing point depression and boiling point elevation equations.
