Chemical Studies on Hot Springs. IX : Chemical Analysis of Chloride.

Abstract

Effects of pH values on the amounts of chloride determined by five analytical methods were investigated. In titration analysis, a particular error was respectively shown by Mohr, Volhard, and mercuric nitrate method. Uranine solution was unsuitable as the indicator, since remarkable end point was not given. In colorimetric determination by mercuric thiocyanate, however, no difference of color tone was visually observed by various pH values of the solution containing 50 ppm chlor ion.
