Abstract: cf. C.A. 50, 9767h. Lime made from a very pure limestone A contg. 97% CaCO3 and a limestone B of lower purity, contg. 90% CaCO3 and 8% MgCO3, was studied. Electrokinetic potential was detd. by the cataphoretic and electro.ovrddot.osmotic method. The lime milk prepd. from A showed ζ = +13.36 ± 0.41 mv. by electro.ovrddot.osmotic and +13.04 ± 0.25 mv. by cataphoretic method. A good agreement between the 2 methods indicates that there is a negligible electrolytic overflow of liquid in the electroosmotic method. The lime milk prepd. from B showed ζ = 15.4 ± 0.9 mv.
