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

Answer»

all solutions
solutions of non-ELECTROLYTES which neither dissociates nor associates
solutions of electrolytes only
none

Solution :For ISOTONIC solutions `pi_(1)=pi_(2) , C_(1) = C_(2)` is valid only for solutes which neither DISSOCIATE (NONELECTROLYTES) nor associate.
