| Abstract: | A method to determine the water content and the hydrogen chloride content in the gas from the dehydration of bischofite using hydrogen chloride as the protective atmosphere was established. The water was absorbed by phosphorus pentoxide and weighted directly. The hydrogen chloride gas was absorbed by sodium hydroxide solution. The chloride ion is titrated with hydrargyrum nitrate standard solution. The systemic error was eliminated by using correction factor. |
