Question
Write the oxidation and reduction half reactions from the following redox reaction.
2Fe + 2H2O + O2 → 2Fe(OH)2
2Fe + 2H2O + O2 → 2Fe(OH)2
✓
Answer
$\text{Fe}\xrightarrow{\ \ \ }\text{Fe}^{2+}+2\text{e}^-$ (Oxidation)
$\frac12\text{O}_2+\text{H}_2\text{O}+2\text{e}^-\xrightarrow{\ \ \ \ \ \ }\text{2OH}^-$ (Oxidation)
$\frac12\text{O}_2+\text{H}_2\text{O}+2\text{e}^-\xrightarrow{\ \ \ \ \ \ }\text{2OH}^-$ (Oxidation)
