Properties of cobalt soaps in a benzene-methanol mixture

The behaviour of cobalt soaps (laurate, myristate, palmitate) in a benzene- methanol mixture (1 : 1 V/V) was studied by conductometric, surface tension and parachor methods. The conductances of these soaps were determined at t emperatures of 40 and 50 degreesC and confirm that these soaps behave as a simple electrolyte in mixed solvents. The surface tension and parachor resu lts confirm that the soap molecules do not show appreciable aggregation in dilute solutions below the c.m.c., and the area covered by one mol of soap lies in the range of 21.1-25.3 x 10(-20) m(2).
