Light‐scattering by a number of solvents, in conjunction with data on solutions of Ludox, saccharose‐octa‐acetate, and polystyrene

Abstract

Abstract A light‐scattering apparatus is described. It is calibrated by means of Ludox solutions, whose absolute turbidities are determined in transmission measurements. A check on the method is made with solutions of sucrose octa‐acetate in methanol and of the international polystyrene sample 2 (2‐1‐49) in butanone and in toluene. Finally, the turbidities of various solvents are reported, and compared with values quoted from the literature (Sect. 7).
