Question

Equimolal solutions in the same solvent have ______.

Options

• different boiling and different freezing points.

• same boiling and same freezing points.

• same freezing point but different boiling points.

• same boiling point but different freezing points.

Answer 1

Equimolal solutions in the same solvent have same boiling and same freezing points.

Explanation:

Colligative properties, such as boiling point elevation and freezing point depression, depend solely on the concentration of solute particles in a solution, not the specific identity of the solute (as long as it is a non-volatile solute). In equimolal solutions, the number of moles of solute is the same for both solutions in the same solvent. Therefore, the colligative properties, which include boiling point and freezing point, will be the same.
