## Balancing Redox Reactions Using the Half Reaction Method### Task3. Balance the following reactions using the half reaction method:a. \( \text{Cd(s)} + \text{Cr}_2\text{O}_7^{2-}(\text{aq}) \rightleftharpoons \text{Cd}^{2+}(\text{aq}) + \text{Cr}^{3+}(\text{aq}) \) [acidic solution]b. \( \text{O}_2(\text{aq}) + \text{SO}_2(\text{aq}) \rightleftharpoons \text{SO}_4^{2-}(\text{aq}) + \text{H}_2\text{O}_2(\text{g}) \) [basic solution]c. \( \text{S}_2\text{O}_3^{2-}(\text{aq}) + \text{Br}_2(l) \rightleftharpoons \text{SO}_4^{2-}(\text{aq}) + \text{Br}^1(\text{aq}) \) [acidic solution]d. \( \text{Al(s)} + \text{MnO}_4^{-1}(\text{aq}) \rightleftharpoons \text{Al(OH)}_4^{-1}(\text{aq}) + \text{MnO}_2(s) \) [basic solution]### ExplanationFor the reactions listed, use the half reaction method to balance redox reactions in both acidic and basic solutions. The approach involves separating the oxidation and reduction processes, balancing the atoms and charges, and then combining the half-reactions to form a balanced overall reaction.

We need to balance the reactions using half cell reaction method. In this method the given redox reaction is separted into two half cell i.e. oxidation half cell and reduced half cell and then each of them is individually balanced and further added up to give the total reaction in balanced form.
