Chrome alum or Chromium(III) potassium sulfate is the potassium double sulfate of chromium. Its chemical formula is KCr(SO 4) 2 and it is commonly found in its dodecahydrate form as KCr(SO 4) 2 ·12(H 2 O). It is used in leather tanning. [1]
Hydrated chromium(III) sulfate, Cr 2 (SO 4) 3 ·18H 2 O, (CAS #13520-66-6) is a violet solid that readily dissolves in water to give the metal aquo complex, [Cr(H 2 O) 6] 3+. The formula of this compound can be written more descriptively as [Cr(H 2 O) 6 ] 2 (SO 4 ) 3 ·6H 2 O. Six of the eighteen water molecules in this formula unit are water ...

dirubidium chromium sulfate hexahydrate Cs Cr Cs 2 [Cr(H 2 O) 6](SO 4) 2 [23] dicaesium chromium sulfate hexahydrate ND 4: Cr (ND 4) 2 Cr(SO 4) 2 · 6 H 2 O [23] dideuterated ammonium chromium sulfate hexahydrate bright blue, formed from with ammonium sulfate in minimal water under nitrogen gas. Stable in air from oxidation, but may dehydrate.
2 O, a dark violet crystalline double sulfate of chromium and potassium, was used in tanning. In general, alums are formed more easily when the alkali metal atom is larger. This rule was first stated by Locke in 1902, [ 34 ] who found that if a trivalent metal does not form a caesium alum, it neither will form an alum with any other alkali ...
