THE QUANTITATIVE DETERMINATION OF THE CHLORIDS IN THE URINE

Abstract

The methods commonly described for the determination of the chlorids in the urine are, with the exception of those of Mohr and Volhard, either too long and complicated for the busy clinician or too inaccurate for anything approaching scientific work.The method described by Mohr,1 in which the chlorids are precipitated by a standardized solution of silver nitrate, using potassium chro- mate as an indicator, is a rapid and convenient process.It uniformly gives too high results,2 however, as the silver also precipitates the uric acid, purin bases, urinary pigments, etc., and therefore is not satisfactory
