Saturated remedies in distilled drinking water contain sulfide at approximately 4 × 10−6 mol/liter. The solubility in h2o made up of hydrogen sulfide is considerably lower, but of a similar order of magnitude. In alkaline solution, the sulfides dissolve, with development of thioarsenites or thioarsenates. These sulfides are decomposed by https://peterq012bzw0.vidublog.com/profile
