To determine which element is reduced or oxidized, we must identify the changes in their oxidation states. Compare the oxidation number of the element on the reactant side and on the product side.
Remember the mnemonics:
PbS(s) + 4 H2O2(aq) → PbSO4(s) + 4 H2O(l)
Recall the rules for the oxidation states of some elements
Which element is oxidized and which is reduced in the following reaction?
PbS(s) + 4H2O2(aq) → PbSO4(s) + 4H2O(l)
Express your answer as chemical symbols separated by a comma.
