BaSO 4 is an inorganic compound with the chemical name Barium Sulphate. Barium Sulphate is composed of a barium cation and the sulphate anion. The sulphur is attached to four oxygen atoms. BaSO 4 is a sulphate salt of barium and is found as the mineral barite In this video we had discussed about Estimation of Barium Sulphate by Gravimetric Analysis1. Principle of Estimation of Barium Sulphate by Gravimetric Analys.
4) Suppose that a small portion of the sulfate precipitated as lead sulfate rather than as barium sulfate. How this would change the result of the analysis? 5) From the following list, identify the interfering species in the sulfate determination method used in this experiment: Pb2+, Na+, NO 3-, CO 3 2-, PO 4 3-.
1.2 This method is suitable for all concentration ranges of sulfate (SO 4-2); however, in order to obtain reliable readings, use a sample aliquot containing not more than 40 mg/L of SO 4-2. 1.3 The minimum detectable limit is approximately 1 mg/L of SO 4-2. 2.0 SUMMARY OF METHOD 2.1 Sulfate ion is converted to a barium sulfate suspension underGravimetric analysis is a quantitative evaluation of laboratory techniques based primarily on the size of an analyte’s mass. Gravimetric analysis can be used in real life for many users, such as monitoring lead levels in water for human consumption, which, if not monitored, could lead to poisoning and death.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.
