unbalanced equations for two redox reactions, in which \( \mathrm{SO}_{2} \) is involved, are wn below. action 1: \( \mathrm{SO}_{2}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{~S}(\mathrm{~g}) \rightarrow \mathrm{S}(\mathrm{s})+\mathrm{H}_{2} \mathrm{O}(\ell) \) Explain what is meant by the term redox reaction. \( \mathrm{SO}_{2}(\mathrm{~g})+\mathrm{KMnO}_{4}(\mathrm{~s})+\mathrm{H}_{2} \mathrm{O}(\ell) \rightarrow \mathrm{MnSO}_{4}(\mathrm{aq})+\mathrm{K}_{2} \mathrm{SO}_{4}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{SO}_{4}(\mathrm{aq}) \) Write down the oxidation number of Mn in: 9.2.1 \( \quad \mathrm{KMnO}_{4} \) 9.2.2 \( \quad \mathrm{MnSO}_{4} \) Is Mn in Reaction 2 OXIDISED or REDUCED? Give a reason for the answer. In which reaction, Reaction 1 or Reaction 2, does \( \mathrm{SO}_{2} \) act as an oxidising agent? Give a reason for the answer. Write down the oxidation half-reaction in Reaction 1. Use the Table of Standard Reduction Potentials and write down the balanced net ionic equation for Reaction 1 . Show the half-reactions and how you arrived at the final equation.
