The van t hoff factor offers insight on the effect of solutes on the colligative properties of solutions. The van t hoff factor can be defined as the ratio of the concentration of particles formed when a substance is dissolved to the concentration of the substance by mass. Van t hoff factor describes how colligative properties vary from the actual value.
