The turbidity of an aqueous solution of sodium dodecylbenzene sulfonate (SDBS, molecular weight of 349 g/mole) was determined in a light scattering photometer at various concentrations above its CMC. The optical constant H for this system has a value of 4.00 x 10-6 mole cm2g2. Results are shown in the following table. 2.68 7.58 13.30 22.15 Conc of SDBS x 103 (g/cm3) Turbidity x 104 (cm:1) 1.09 1.80 2.08 2.31 Why does turbidity increase with concentration? Calculate the molecular weight of the aggregate in the aqueous solution, the value of the solute-solvent interaction constant and the degree of aggregation. (10 marks)
