CHROMIUM POTASSIUM SULFATE Usage And Synthesis
Chemical PropertiesAlso known as chrome alum and chrome potash alum, CrK(S04)2·12H20 is dark, violet-red crystals that are efflorescent and soluble in water. Derived by reducing potassium dichromate in dilute sulfuric acid with sulfurous acid. Used in tanning(chrome-tan liquors), textile dye(mordant), photography (fixing bath)and ceramics.
Chemical PropertiesChromium potassium sulfate is a crystalline compound whose color may range from violet-red to black
UsesTanning (chrome-tan liquors), textile dye (mordant), photography (fixing bath), ceramics.
General DescriptionThe higher the pH more is the chromium (III) (crystal growth suppressor) adsorbed, on the surface of potassium sulfate crystal powder which is suspended in saturated solutions.
HazardToxic by ingestion.
Safety ProfileMutation data reported. Questionable carcinogen. When heated to decomposition it emits toxic fumes of K2O. See also CHROMIUM COMPOUNDS and SULFATES.
Potential ExposureThis material is used in tanning of leather; dyeing of fabrics; manufacture of glues and gums, chromium salts; ink, photographic emulsions, and ceramics
ShippingUN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
IncompatibilitiesContact with magnesium, aluminum may cause fire and explosion hazard.
