Three chromium(III) sulfates are well characterized: A variety of other chromium(VI) sulfates are known, but also contain hydroxide or oxide ligands. Free samples program. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers. The pentahydrate is a blue solid that dissolves readily in water. Wash thoroughly after handling. The content of Co 3 O 4 was found to be the dominant factor for the degree of blackness. Solubility in water, . It is commonly used in tanning leather. Several closely related hydrated salts are known. Fine free flowing, Dark green color powder. The precise nature of the sulfate-complexes in solution cannot be described, only a general outline, like the one given here, is possible. These sulfato-complexes have a green color. 42% or 50% may be obtained by the addition of sodium carbonate, these are often used in combination with sodium formate. These salts are usually either violet or green solids that are soluble in water. In the presence of chloride ions (for example with chromium(III) chloride), the most commonly observed color is green. Reactions of chromium(III) ions in solution The simplest ion that chromium forms in solution is the hexaaquachromium(III) ion - [Cr(H 2 O) 6] 3+. Basic Chromium Sulfate is mainly used in tanning of processing leather industry or synthesis of other chromium based re-tanning agents and production of chromic compound. Chromic sulfate is a dark green to violet crystalline material. Covington, A. D.; Lampard, G. S.; Menderes, O.; Chadwick, A. V.; Rafeletos, G.; O'Brien, P.
