Question
Identify from the following reaction the reactants that undergo oxidation and reduction.
2Ag2O → 4 Ag + O2 ↑
Solution
In a reaction, silver oxide is changing to silver. That is, oxygen is being removed from silver oxide. Removal of oxygen from substance is called reduction, so silver oxide undergoes reduction.
