Determination of sulphate in water
WebBackground: Sulfate ions can be determined by titrating with a solution of barium chloride. The formation of the insoluble barium sulfate precipitate is a strong exothermic reaction that can be followed by thermometric titration. In thermometric titration, the change in reaction heat (i.e. enthalpy change) is monitored in the course of a titration.
