Decide whether each chemical reaction in the table below is an oxidation-reduction ("redox") reaction. If the reaction is a redox reaction, write down the formula of the reducing agent and the formula of the oxidizing agent.

Which method is used to make fake gold coins? Additive Plating: A plating reaction where metal cations are reduced by an electron donor in solution. The reduced cations coat the surface of an object. OR Displacement Plating A plating reaction is where metal cations are reduced by metals on the surface of an object. The reduced metal cations become neutral atoms and coat the object, replacing the oxidized metal atoms that become metal cations.

Provide two written definitions of an oxidation-reduction reaction and for each definition tell which reactant is reduced and which is oxidized. Then tell which of the two definitions is the most comprehensive.

OH Excess Oxidant
