Balance the following redox reactions by ion-electron method.
`H_(2)O_(2)(aq)+Fe^(2+)(aq)toFe^(3+)(aq)+H_(2)O(l)` (in acidic solution)

Explanation

To balance the redox reaction \( H_2O_2(aq) + Fe^{2+}(aq) \rightarrow Fe^{3+}(aq) + H_2O(l) \) in acidic solution using the ion-electron method, follow these steps:

### Step 1: Identify Oxidation and Reduction Half-Reactions
- **Oxidation Half-Reaction**: The oxidation involves the conversion of \( Fe^{2+} \) to \( Fe^{3+} \).
\[ Fe^{2+} \rightarrow Fe^{3+} + e^- \]
