Determination of cobalt as tellurite

Summary Cobalt has been determined gravimetrically by precipitation as cobalt tellurite and by titration of the excess tellurite added. Effect of temperature of drying and addition of excess of tellurite was studied. Composition of the cobalt tellurite has also been determined.Sincere thanks of the authors are due to Prof. S. S.
