本文介绍了一种简单,准确的标定氯化高汞溶液之方法。这种新方法是基于用硫化氢与高汞反应时释出氢离子,然后用标准氢氧化钠液滴定之。作者用甲基紫作指示剂,终点敏锐。标化0.1M和0.01M之氯化高汞溶液的偏差在±0.4％以内。
This article describes a simple and accurate method for calibrating high-mercury chlorinated solutions. This new method is based on the release of hydrogen ions when hydrogen sulfide is reacted with high mercury and then titrated with standard sodium hydroxide. The authors used methyl violet as an indicator, the end point sensitive. Standard deviation of 0.1M and 0.01M chloride high mercury solution within ± 0.4%.
