Explain why the van't Hoff factor for K2SO4 is less than its predicted value.   The hydrated K⁺ and SO42- ions attract one another and effectively increase the number of free particles in the solution. The hydrated K⁺ and SO42- ions attract one another and effectively reduce the number of free particles in the solution. The number of moles of formula units is greater than the number of free particles in the solution. The hydrated K⁺ and SO42- ions repel one another and effectively reduce the number of free particles in the solution.

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.
