摘要：A number of methods for the determination of chloride in urine hitherto used was investigated thoroughly, and the ‘Schales’ titration method with mercuric nitrate solution was found to beethe most favorable procedure. But, when applied to the urine, this method also had the following unfavorable points: 1), the end point of the titration was found to be somewhat obscur, 2), this fault was much more significant with acidic urine, and 3), in alkaline urine, the titration medium became red by the addition of diphenylcarbazone. By the use of the sample solution diluted previously ten folds with N/10 acetic acid, and also of the reagent solution diminished to one-half of its HNO₃ concentration to the original report, the simple, rapid, and accurate determination can be realized.
