THE BASIC PRINCIPLES OF ARSENIC LLL OXIDE

Saturated remedies in distilled h2o comprise sulfide at approximately 4 × ten−six mol/liter. The solubility in h2o made up of hydrogen sulfide is considerably lessen, but of the same order of magnitude. In alkaline Answer, the sulfides dissolve, with formation of thioarsenites or thioarsenates. These sulfides are decomposed by cold water in the
