Saturated solutions in distilled drinking water have sulfide at approximately 4 × ten−6 mol/liter. The solubility in h2o containing hydrogen sulfide is rather reduced, but of the same purchase of magnitude. In alkaline solution, the sulfides dissolve, with formation of thioarsenites or thioarsenates. These sulfides are decomposed by chilly water https://andreshezbb.tdlwiki.com/1278101/the_greatest_guide_to_arsenic_lll_oxide
