Question

When solute undergoes dissociation in solution, the value of i is ______ than 1.

Answer 1

When solute undergoes dissociation in solution, the value of i is greater than 1.

Explanation:

Dissociation increases the number of solute particles in the solution (e.g., \[\ce{NaCl -> Na+ + Cl-}\]). Since colligative properties depend on the number of particles, the van’t Hoff factor (i), which measures the effect of particle change, becomes greater than 1. This reflects the increase in effective concentration of solute particles in the solution.
