Due to hydrochloric acid response with barium chloride, barium sulphates are precipitated as barium. sulphate.
As per B.P, the principle from the limit test is dependent on the formation of brownish coloration when sodium sulfide is extra to your dilute solution made up of lead salts. The depth of colour differs depending on the quantity of lead current.
The colour of chloroform layer is not more intensive than that obtained by treating in the identical method a volume of lead nitrate Alternative, one ppm
