A student removes H+ ions from the reaction shown. Will the dilution turn more green or more purple ?

3MnO42-(aq) + 4H+ (aq) >><< 2MnO-4(aq) + 2H2O(l) + MnO2(aq)

1 answer

The removal of H+ ions will shift the equilibrium to the left, which means there will be more MnO42- ions present. Since MnO42- is green and MnO4- is purple, the dilution will turn more green.
