WebCr 2 O 7-2 + 2 OH-⇌ 2 CrO 4-2 + H 2 O. Step 2: Determine the oxidation number of Cr in CrO 4-2: Formula to find the oxidation number of an atom in a compound is. T o t a l c h a r g e … 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 ...
