Precipitation of barium sulfate: Experimental

Oct 01, 2006· Barium sulfate was precipitated from mixtures of aqueous sodium sulfate and barium chloride solutions. Stock solutions were prepared from the corresponding crystalline reagent grade solids, barium chloride dihydrate (Roth, 4453.4, pro analysis) and sodium sulfate (Merck, 1.06649.5000, pro analysis), dissolved in demineralized water.

16.3: Precipitation and the Solubility Product Chemistry

Aug 14, 2020· Example \(\PageIndex{3}\): barium milkshakes. Barium sulfate is used in medical imaging of the gastrointestinal tract. Its solubility product is \(1.08 \times 10^{−10}\) at 25°C, so it is ideally suited for this purpose because of its low solubility when a “barium milkshake” is consumed by a patient.

THE DETERMINATION OF SULFUR AS BARIUM SULFATE

and Berzelius, as early as 1829, claimed that barium sulfate, even when precipitated by an excess of barium chlorid from a solu­ tion of potassium sulfate, is always contaminated by the last salt. Rose3 states that the precipitate contains both potassium chlorid and barium chlorid even after thoroly washing with hydrochloric acid.
