WebOxidation reactions involve: 1. Addition of oxygen: C + O2 → CO2 (oxidation of carbon) 2. Addition of electronegative element: Fe + S → FeS (oxidation of Iron) 3. Removal of hydrogen: H2S + Br2 → 2 HBr + S (oxidation of sulphide) 4. Removal of electropositive elements: 2 KI + H2O2 → I2 + 2 KOH (oxidation of iodide) WebBecause Group 1 metals always have an oxidation state of +1 in their compounds, it follows that the hydrogen must have an oxidation state of -1 (+1 -1 = 0).
