The determination of sulphate is always by means of converting the sulphate into BaSO4.The barium sulphate is more stable than barium chromate.So when we add barium chromate to the sulphate solution,the chromate can be replaced by sulphate,forming barium sulphate,which is more stable,the quantity of the chromate that is determined by spectropho tometry can be used to calculate the quantity of the sulphate.
Key words: sulphate; barium chromate; barium sulphate; spectrophotometry
