Osmotic pressure data for different concentrations of C17H35COONa: C = 0.01, 0.02, 0.03, 0.04 M and π/RT = 0.02, 0.04, 0.058, 0.076. Select correct information:

Question

Prashant Kotian · Accepted Answer

Correct answer: A,B,C. At 0.01 and 0.02 M, π/RT = 2C, indicating complete dissociation (a). Above 0.02 M, π/RT < 2C due to association (c). At 0.04 M, association is significant (b). Colloidal mixtures are heterogeneous (d is false).
