A chromium(III) oxide coproduct is generated which is readily extracted into sulfuric acid. Potassium chromium sulfate has been used in the leather industry for tanning the hides (nowadays it is replaced by basic chromium sulfate, Cr(OH)SO 4 ). The solution reddens litmus and is an astringent . A uniform black coating forms at current densities over 30 A/dm 2 . It finds applications in the synthesis of other chromium based re-tanning agents and production of chromic compound. We propose an electrolyte based on chromium sulfate (1 mole/liter Cr(III)) and containing both formic acid and carbamide (urea). n H 2 O. Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece Additionally, ill-defined but commercially important "basic chromium sulfates" are known. Most important commercially is basic chromium sulfate, which is thought to be [Cr2(H2O)6(OH)4]SO4 (CAS#39380-78-4). There are several factors to consider when choosing between sulfate and chloride-based baths for trivalent chromium plating. 2.6 Reaction between chromium(III) sulfate and nitrate or potassium chloride 2.7 Reaction between potassium hydroxide or carbonate, chromium(III) hydroxide and sulfuric acid 3 Influence of impurities 4 Notes 5 Storage conditions 6 Basic chromium sulfate is produced from chromate salts by reduction with sulfur dioxide, although other methods exist. The trivalent chromium ion, once complexed with the polyhydric alcohol derivative, is not easily converted to hydrated complexes. High purity, submicron and nanopowder forms may be considered. CHROMIUM SULPHURICUM- chromic sulfate pentadecahydrate pellet Under Review - Editing is pending for RxNorm. Extraction of chromite ore with sulfuric acid in the presence of some chromate gives solutions of chromium(III) sulfate contaminated with other metal ions.

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. Solubility in water, . Chromic sulfate is a dark green to violet crystalline material. Chromium Sulfate Solution Cr2(SO4)3 bulk & research qty manufacturer. It is commonly used in tanning leather. In the presence of chloride ions (for example with chromium(III) chloride), the most commonly observed color is green. The precise nature of the sulfate-complexes in solution cannot be described, only a general outline, like the one given here, is possible. The hydrated salts of chromium sulfate can also be produced, albeit impure, by extraction of various other chromium compounds, but these routes are not economically viable.. Other chromium(III) hydroxides have been reported.[3]. There are 3 complex minerals being, in part, Cr(III) sulfates: bentorite, reddingtonite, and ptnisite. Wash thoroughly after handling.

Potassium chromium sulfate, KCr(SO 4) 2 12H 2 O, or chromium alum (1), forms violett octaeders and is highly soluble in water. [4][5] The reduction could formally be written: Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced). Keep out of moisture. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal . Keep away from sunlight and heat sources.
