MHT CET Chemistry question

At low concentrations the statement that equimolal solution under a given set of experimental conditions have equal osmotic pressure is true for

(A)All solutions
(B)Solutions of non-electrolytes onlyCorrect
(C)Solutions of electrolytes only
(D)Colloidal solutions

Answer: (B)

Solution

Osmotic pressure depends on the number of particles; equimolal solutions have equal osmotic pressure only if the solutes do not dissociate or associate, i.e.
