    by a process called gravimetric analysis. Gravimetric analysis is the quantitative isolation of a substance by precipitation and the weighing of the precipitate. In this experiment‚ sodium sulphate was allowed to react with barium sulphate to form a white precipitate of barium sulphate. This precipitate was then washed‚ filtered and dried‚ to ensure that there are no impurities and water molecules present‚ before it was being weighed. The amount of sulphate obtained was calculated to be 0.2028g and

    using semimicro scale gravimetric procedure. First by weighing the sample before starting we knew how much unknown substance we had. Then by mixing it with distilled water we made a solution in which we had a precipitate after adding 1 to1.5 ml of Barium Chloride. We also added HCL 1M before BaCl2 to eliminate the chance of formation of another precipitate such BaCO3. Then we extracted the supernatant liquid and dried out
