Gravimetric Analysis report

SynopsisThe objective is to determine the meter of sulphate in anhydrous atomic number 56 sulfate precipitate by gravimetric method. gravimetric method is by the quantitative inclination of the mass of anhydrous Barium sulphate precipitate. Barium sulphate precipitate is take in when Barium Chloride is added excessively to a hot given Sulphate solution slightly acidified with intemperate Hydrochloride acid. The white precipitate of hydrate Barium Sulphate form is than deport, filtered out, washed and dried than still down in a desiccator. Anhydrous Barium Sulphate is formed and weight apply analytical balance. We will determine that the mass of Barium Sulphate precipitate form is 0.1990g and with the fellowship of its chemical composition, we can direct the get along of Sulphate. From these, we found that standard of Sulphate is 0.0820g. And the major experimental finding is that gravimetric corroborate is one of the about accurate and precise methods of macro-q uantitative analysis as we can omen till high figure accuracy. ObjectiveThe habit of this experiment by gravimetric method is to determine the amount of Sulphate in a solution. In addition, to learn to stand out nothingness filtration of Barium Sulphate precipitate and single-valued function a desiccator correctly. TheoryThe amount of Sulphate is determined quantitatively from Barium Sulphate by gravimetric method.

This determination consists of belatedly adding, with bustling stirring a dilute solution of atomic number 56 chloride to a hot solution of the Sodium Sulphate which is slightly acidified with conc entrated hydrochloride acid for the removal ! of impurities and preventing carbon dioxide in the air from reacting to barium to form barium carbonate precipitate. Dilute and hot solutions with lento adding and effective stirring are done to decrease the period of contamination of impurities. Barium Sulphate precipitate form is allowed to digest which can help to reduce the amount of co precipitation. Co precipitation may result in excess mass...
