Title: Determination of the content of barium in barium chloride using barium sulphate volumetric precipitation method in ethanol-water medium
Abstract: It is put forward that the content of barium in barium chloride is determined using barium sulphate volumetric precipitation method in ethanol - water medium. After the sample is dissolved in the ethanol and water medium whose pH is 2.0 - 3.0, the barium ion is titrated by using Na2SO4( standard solution. The result shows that, the modified method is simple to operate, efficient and accurate, and it has little disturbance. Compared with weight method, the relative error of the method is less than 0.5%, which indicates that the accuracy of the method is close to that of weight method; its relative standard deviation is 0.20% , which indicates the repeatability of the method is very good. Therefore, the method is a quick analysis method, which can be used not only in instruc-tional experiments for students but also in field determination.
