Abstract : The sulphate limit test is dependent on the reaction between soluble sulphate and BaCl2 in the presence of alcohol and potassium sulphate. Deposition of solid sulphate particles, such as BaSO4 (For this purpose, BaCl2, alcohol, and a small amount of potassium sulphate are utilised. The alcohol prevents supersaturation, while the potassium sulphate increases the sensitivity of the test by providing an ionic concentration in the reagent that just exceeds the solubility product of BaSO4.). The opalescence/turbidity produced by the sample under test is compared to the opalescence/turbidity produced by the reference sample against the dark backdrop.
