Also 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.
Chromium potassium sulfate is a crystallinecompound whose color may range from violet-red to black.Molecular weight =287.3; Freezing/Melting point =89℃;Soluble in water

Tanning (chrome-tan liquors), textile dye (mordant), photography (fixing bath), ceramics.
The 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.
Mutation data reported.
Questionable carcinogen. When heated to
decomposition it emits toxic fumes of K2O.
