Why is chromium acetate diamagnetic?
Each Cr(II) ion has 4 d electrons but the complex is found to be diamagnetic which is explained by the formation of a quadruple bond between the two metal ions.

Is chromium III acetate soluble in water?
Chromium(III) Acetate Hydroxide moderately water soluble crystalline Chromium source that decomposes to Chromium oxide on heating.
Does chromium oxidize?
Chromium (II) oxide Chromium amalgam can also be oxidized by oxygen in the air: 2Cr/Hg + O₂ = 2CrO + 2Hg. With diluted oxidizing acids (nitric, sulfuric) chromium does not react. Chromium II oxide also does not react with alkalis.
How to prepare anhydrous dichromium (II) tetraacetate?
Chromium metal reacts with acetic acid and hydrobromic acid in the open to form anhydrous chromous acetate. ► Anhydrous dichromium (II) tetraacetate is prepared by a one-pot reaction. ► Chromium metal reacts with hydrobromic and acetic acid in the open. ► This method is superior to all reported strictly anaerobic multi-step procedures.
