... OH Ag(s) + CN (aq) + O2 (g) Ag(CN)2-(aq) Oxidation: CN-(aq) + Ag(s) Ag(CN)2-(aq) Since we need two cyanide ions to form the complex, add two to the reactant side of the equation. Silver is also oxidized, so it looses an electron, so we add one electron to the product side. 2 CN-(aq) + Ag(s) Ag(CN)2- ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
