On The Stability and Electrokinetic Potential of Ferric Hydroxide Sol

A fairly pure and stable ferric oxide sol has been prepared by a slight modification of Graham's method, with a view to ascertaining the existence of any relation between the stability and electrokinetic potential. The true zeta potential found for rapid rate of coagulation is 30.7 m.v. and that for ferric oxide gels is 46.5 m.v.
