The unbalanced equation for the redox reaction between acidified manganate(VII) ions and sulfur dioxide is shown below.
…MnO4−(aq)+…SO2(g)+…H2O(l)→…Mn2+(aq)+…SO42−(aq)+…H+(aq) \dots \text{MnO}_4^-(\text{aq}) + \dots \text{SO}_2(\text{g}) + \dots \text{H}_2\text{O}(\text{l}) \rightarrow \dots \text{Mn}^{2+}(\text{aq}) + \dots \text{SO}_4^{2-}(\text{aq}) + \dots \text{H}^+(\text{aq}) …MnO4−(aq)+…SO2(g)+…H2O(l)→…Mn2+(aq)+…SO42−(aq)+…H+(aq)Which coefficients for SO2(g)\text{SO}_2(\text{g})SO2(g) and H+(aq)\text{H}^+(\text{aq})H+(aq) will balance this equation?
