In performing an experiment on freezing point depression, the solution was prepared by dissolving 2.25 g of salt in 20.00 mL distilled water (density = 0.997 g mL-1; Tf = 0 °C; kf = 1.86 °C m-1). We determined the freezing point of the solution to be -3.48 °C. We later found out that the salt we used was sodium chloride that was contaminated with potassium chloride. Calculate ΔTf for the experiment.

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.
