Balance the following redox reaction using the half reaction method;S2O3 2-(aq) + I2(aq)—-> I-(aq) + S4O6 2- (aq) The Correct Answer and Explanation is : Step 1: Write and Balance the Oxidation Half-Reaction Oxidation occurs when a species loses electrons. Here, thiosulfate (( S_2O_3^{2-} )) is oxidized to tetrathionate (( S_4O_6^{2-} )). Final oxidation half-reaction:[2S_2O_3^{2-}
