The main objective of this experiment is to find out the amount of sulphate which is found quantitatively in barium sulphate using a method known as gravimetric analysis.
The procedure to carry out the experiment involves a hot, unknown sulphate solution, that is to have dilute hydrochloric acid added to it, and the addition of dilute barium chloride to the solution as it is heated. The mixture is to then be heated till boiling and tested for complete precipitation before filtering using a method known as suction filtering, cleaning using deionised water and drying the precipitate of barium sulphate in an oven. The quantitative amount is then to be deduced through calculations. The major experimental find to be observed is the concentration of sulphate ions in grams/litre found in barium sulphate precipitate.
