Under slightly acidic conditions, excess barium chloride is added to quantitatively combine with barium ions to produce barium sulfate precipitate. The remaining barium ions are titrated at PH 10 with disodium EDTETRAACETATE solution. During titration, not only are excess barium ions titrated by disodium EDT solution, but calcium and magnesium ions in the raw water are also titrated simultaneously. Therefore, the total hardness in the water sample should be included in the calculation.
