For the redox reaction , the correct coefficients of the reactants for the balanced equation are (, — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Step 1:** Reduction half: $MnO_4^- + 8H^+ + 5e^- \rightarrow Mn^{2+} + 4H_2O$. <br>**Step 2:** Oxidation half: $C_2O_4^{2-} \rightarrow 2CO_2 + 2e^-$. <br>**Step 3:** Balance electrons by multiplying reduction half by 2 and oxidation half by 5. <br>**Net:** $2MnO_4^- + 5C_2O_4^{2-} + 16H^+ \rightarrow 2Mn^{2+} + 10CO_2 + 8H_2O$. Coefficients are 2, 5, 16. [1-34]
