Summary

The results obtained from the studies in the kinetics of coagulation of the chromium arsenate sol by measurements of light extinction at different stages of dialysis show the regions of slow and rapid coagulation and the slow effect of increasing concentration of an electrolyte on the coagulation process.

It has been observed that coagulum formed during coagulation of a pure sol has higher extinction value than of a partially purified sol. This is due to the fact that in the former case the particles formed have denser structure which scatters more light. Further it is observed that at the highest degree of purity of the sol the extinction is again low even after attaining the maximum coagulation. This has been explained on the basis of the formation of lace-like structure in which the individual particles are held more loosely within the frame work in the absence of regular spacing and thereby scattering lesser light and giving lower extinction values.
