Abstract
After a discussion of the conditions of dismutation of Hg2(SCN)2 a method is proposed for the titration of mercurous salts, similar to that of volhard. As a reagent a solution of potassium mercurithiocyanate, which precipitates the mercurous ions, in compounds such as Hg2(SCN)2,is used; a solution of ferric sulphate is used as an indicator. The mercurous and mercuric ions can be determined in a mixture by effecting two titrations, one direct and the other after oxidation, with permanganate.
