Determination of Sulfate in drinking, surface and waste water. Description. the Sulfate is possible using the Ca-ISE and EGTA as titrant. An excess of . aCl2 is added to the water sample to precipitate the sulfate. The not reacted Ba-ions are back titrated with E.
Electrolysis.pdf. Electrolysis of dilute sulfuric acid. The products of electrolysing water acidified with sulfuric acid are hydrogen gas and oxygen gas. Two experimental setups are described, the Hofmann voltameter demonstration (left diagram) and a simple cell (right diagram) for use in schools and colleges for pupils to use.
In an aqueous solution, sulfate ion undergoes the following reaction with barium: Ba2+(aq)+SO 4 2−(aq) ← → BaSO 4 (s) Ksp= Ba2+ SO42− =1.1x10−10 at 25 C Barium sulfate which forms as a crystalline precipitate, is collected on a suitable filter, washed with water, then ignited and weighed. From the mass of BaSO 4,
29 Αυγ 2023 · Most sulfates, including those of \(\ce{Na^{+}}\), \(\ce{K^{+}}\), and \(\ce{NH4^{+}}\), are soluble in water. Exceptions that are insoluble are white lead(II) sulfate and white barium sulfate: \[\ce{BaSO4(s) <=> Ba2+(aq) + SO42-(aq)} \nonumber \] with \(K_{sp} = 1.4 \times 10^{-8}\) \[\ce{PbSO4(s) <=> Pb2+(aq) + SO42-(aq)} \nonumber \]
