QUESTION 10 The molar mass of a compound can be determined by the freezing point depression method. The solution rust be relatively dilute and you must know the molal freezing point depression constant of the solvent, Kf. Which statement regarding Kf is true? Kf should be small so that the solvent will not sublimate. O Kf should be.negative so the freezing point of the solution will decrease. o Kf should be large so the temperature change will be large enough to measure. Kf will change depending ón what solute is dissolved in the solvent.

Concept explainers

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
