Which of the following solutions has higher freezing point ?0.05 M Al_2(SO_4)_3, 0.1 M K_3[Fe(CN)_6] . Justify.

Answer»

Solution : Depression in freezing POINT depends upon the concentration of the solution.` 0.05 M Al_2(SO_4)_3 `has a lower concentration than `0.1 M K_3 [Fe(CN)_6]`solution.
Thus, `0.05 M Al_2(SO_4)_3`gives a lower depression in freezing point. In other words, it will freezeat HIGHER temperature.
