In comparison to a 0.01 M solution of glucose, the depression in freezing point of a 0.01 M solution is _____________.
(i) the same
(ii) about twice
(iii) about three times
(iv) about six times
The answer is the option (iii). Colligative properties only depend on the number of solute. While 0.01 M solution of glucose does not ionize, 0.01 M solution ionizes to produce a single ion and ions.
