In comparison to a \(0.01 \mathrm{M}\) solution of glucose, the depression in freezing point of a \(0.01 \mathrm{M} \mathrm{MgCl}_2\) solution is (Molecular weight of \(\mathrm{MgCl}_2=95\), molecular weight of glucose \(=180\) ).
- A the same
- B about twice
- C about three times
- D about six times
Answer & Solution
Correct Answer
(C) about three times
Step-by-step Solution
Detailed explanation
\(0.01 \mathrm{M}\) solution of glucose does not ionise while \(0.01 \mathrm{M} \mathrm{MgCl}_2\) solution furnishes 3 ions \(\left(\mathrm{Mg}^{2+}+2 \mathrm{Cl}^{-}\right)\)in the solution, hence the value of colligative property of \(\mathrm{MgCl}_2\) solution is about 3…
