Which substance is oxidised in the reaction represented by the ionic equation below? Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s)

Remember OILRIG for oxidation or reduction reactionOxidisation IsLoss Reduction Is GainSo if Zinc goes from neutral charge to 2+ charge, this means it has lost 2 negative charges in electrons, so as oxidation is loss, zinc has been oxidised.
