Answer the following in one or two sentences.

What is van’t Hoff factor?

Solution

van’t Hoff factor (i) is defined as the ratio of colligative property of a solution of electrolyte divided by the colligative property of nonelectrolyte solution of the same concentration.

Thus,

i = colligative property of electrolyte solutioncolligativepropertyof nonelectrolyte solutionof the same concentration

=Tf(Tf)0=Tb(Tb)0=P(P)0=π(π)0

where quantities without subscript refer to electrolytes and those with subscript to nonelectrolytes.
