What Is the Chemical Formula of Chromium III Acetate?

The chemical formula for chromium (III) acetate is notated as Cr(C2H3O2)3. The formula contains the symbol Cr for chromium. The chemical formula for acetate, C2H3O2, uses the symbols C for carbon, H for hydrogen and O for oxygen.

The formula contains three acetate molecules for every molecule of chromium (III) to balance out the charges. The combined charges of the atoms in the acetate compound hold a charge of minus one. Therefore, the formula requires three molecules of acetate to balance out the plus three charge of a single molecule of chromium. The charge on the C2 is neutral, with one atom charged to plus four and the other to minus four.
