In coparison to a 0.01 M solution of glucose, the depression in freezing point of a 0.01 M `MgCl_(2)` solution is……

Options

A. the same
B. about twice
C. about three times
D. about six times

Answer

C

Explanation

`DeltaT_f=iK_fm`
For glucose , i=1
For `MgCl_2` , i=3
Thus, the depression in freezing point `(DeltaT_f)` of a 0.01 M glucose solution.
