Chromium III Sulfate Formula: Structure, Properties, Examples
Three chromium(III) sulfates are well characterized: • Anhydrous chromium(III) sulfate, Cr2(SO4)3, (CAS #10101-53-8) is a violet solid that dissolves in water upon addition of a reducing agent, which generates chromium(II) sulfates. • Hydrated chromium(III) sulfate, Cr2(SO4)3·18H2O, (CAS #13520-66-6) is a violet solid that readily dissolves in water to give the metal a… WebChromium metal is not dissolved by nitric acid, HNO 3 but is passivated instead. Cr (s) + 2 HCl (aq) Cr 2+ (aq) + 2 Cl − (aq) + H 2 (g) Cr (VI) is reduced to Cr (III) by ascorbic acid (reductive coefficient = 3.473*10 6 M -1 *s -1) [3].
