Question
**Balancing a Redox Reaction in Basic Solution** The unbalanced redox reaction given is: \[ \text{Cr(OH)}_3(s) + \text{Fe}^{3+}(aq) \rightarrow \text{CrO}_4^{2-}(aq) + \text{Fe}^{2+}(aq) \] ### Explanation: 1. **Reactants:** - Solid chromium(III) hydroxide, \(\text{Cr(OH)}_3(s)\). - Aqueous iron(III) ions, \(\text{Fe}^{3+}(aq)\). 2. **Products:** - Aqueous chromate ions, \(\text{CrO}_4^{2-}(aq)\). - Aqueous iron(II) ions, \(\text{Fe}^{2+}(aq)\). ### Diagrams: - **Electron Transfer Diagram:** - An arrow indicates the transfer of electrons (\(e^-\)) during the redox reaction. - Different boxes are likely representing individual steps involved in balancing oxidation and reduction half-reactions, using electrons. This diagram is visualizing the electron exchange necessary for balancing redox reactions, especially useful in educational settings to explain oxidation and reduction processes.
