WebMay 16, 2024 · The dichromate ($\ce{Cr2O7^2-}$) ions are strong oxidizing agents at low pH. During the redox process, each chromium atom in the dichromate ions (oxidation … WebSep 30, 2024 · Let us consider the oxidation number of Cr is x. Since Cr2 (SO4)3 is a molecule, it's oxidation number is 0. And the oxidation number of (SO4) is always -2. So, … WebApr 13, 2024 · There are seven oxygen atoms, so the total charge is −2 ⋅ 7 = −14. Let x be the oxidation number of two chromium atoms. So, we got: x + ( − 14) = −2. x − 14 = −2. x = 12. So, two chromium atoms have a total oxidation number of +12. Since one is not more electronegative than the other, we can divide the number by two to get one ... latymer school hire
