the invention u043au0430u0441u0430u0435u0442u0441u00a0 analytical chemistry in particular quantitative u043eu043fu0440u0435u0434u0435u043bu0435u043du0438u00a0 chloride - ion in u0445u043bu043eu0440u0438u0440u043eu0432u0430u043du043du043eu043c u0442u0440u0438u043du0430u0442u0440u0438u0439u0444u043eu0441u0444u0430u0442u0435. the purpose of u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 - improvements in the accuracy and repeatability of the method. the last lead were inferior by disappearing into a sample in water in the presence of acetone (volumetric ratio of 1: 1.5 to 3 and u0442u0438u0442u0440u043eu0432u0430u043du0438u0435u043c silver nitrate. in this case, the error analysis is not more than 5 rh.% to (- 45) rh.% in a case and the reproducibility (average standard deviation from the average) u0441u043eu0441u0442u0430u0432u043bu00a0u0435u0442 29%. 2, table 2).
