Sulphate Gravimetric Method for Sulphate Determination: Theory: Nearly all sulphates in water can be precipitated as BaSO 4 on reaction with barium chloride (BaCl 2) under acidic conditions. Since this compound has very low solubility product, the precipitated BaSO 4 can be filtered and the residue weighed. Sulfate concentrations are determined in mine water by gravimetric, titrimetric, colorimetric, turbidometric, ion chromatographic, inductively coupled plasma absorption spectrophotometric, and other methods. Accurate sulfate measurement of mine water can be difficult due to interfering groups, cations, and anions, mainly arsenate (AsO4 3−) and .
