Hi,hope this helps you..
The determination of sulphate concentration in water by indirect titration is an instructive experiment that is easily implemented in an analytical chemistry laboratory course. A water sample is treated with excess barium chloride to precipitate sulphate ions BaSO4(s). The unprecipitated barium ions are then titrated with EDTA. By performing this experiment,you will be exposed to a number of important concepts including chelation,indirect and back titration,precipitation and water quality
