Van't Hoff factor (i)
$\text{=}\frac{\text{Number}\text{of}\text{particles}\text{present}\text{in}\text{the}\text{solution}}{\text{Number}\text{of}\text{formula}\text{units}\text{dissolved}\text{in}\text{the}\text{solution}}$
$\mathrm{i}>1$indicates the particles in the solution are greater than the formula units dissolved in the solution. This is possible, if the solute undergoes dissociation.
