Question

Which of the following solution will have highest freezing point depression?

पर्याय

• 1 M sucrose

• 1 M KCl

• 1 M glucose

• 1 M urea

Answer 1

1 M KCl

Explanation:

\[\ce{KCl ⇌ K^+ + Cl^-}\]

Because KCl dissociates to form ions, it produces more particles in the solution. The number of solute particles determines the Colligative characteristic. KCl will experience a significant drop in freezing point.
