Question

In comparison to a 0.01 m solution of glucose, the depression in freezing point of a 0.01 m MgCl 2 solution is - (A) same (B) twice (C) three times (D) six times

Tardigrade Admin · Accepted Answer

For glucose i =1 For MgCl 2= i =3 Δ T f propto i (same concentration)

Q. In comparison to a $0.01 m$ solution of glucose, the depression in freezing point of a $0.01 m M g C l_{2}$ solution is -

same

twice

three times

six times

For glucose $i = 1$
For $M g C l_{2} = i = 3$
$Δ T_{f} \propto i$ (same concentration)
