WebTo find the equivalent of potassium dichromate, it is necessary to examine the changes in the oxidation state of Cr in the reactants and products, and in the acidic medium. (Cr 2 O 7 2-→ 2Cr 3). Here, the oxidation state changed (the change was 6 because it changed from 2 × 6 to 2 × 3) to the equivalent of KCr 2 O 7 = 294.18 / 6 = 49.03. WebApr 13, 2024 · Explanation: This is the dichromate ion, Cr2O2− 7. Oxygen is more electronegative than chromium, so it'll take its usual −2 charge here. 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
