Text Solution

AI Generated Solution

To write the half-reactions for the given redox reaction \(2Fe^{3+} + 2I^{-} \rightarrow 2Fe^{2+} + I_{2}\), we need to identify the oxidation and reduction processes occurring in the reaction. ### Step-by-Step Solution: 1. **Identify Oxidation and Reduction:** - In the reaction, iron (\(Fe\)) is reduced from \(Fe^{3+}\) to \(Fe^{2+}\). - Iodide ion (\(I^{-}\)) is oxidized to iodine (\(I_{2}\)). ...
