The normal oxidation potential of zinc referred to the standard hydrogen electrode is 0.76 volt and that of copper is -0.34 volt at `25^(@)C`. When excess of zinc is added to a solution of copper sulphate the zinc displace copper till equilibrium is reached. What is the ratio of concentration of `Zn^(2+)` to `Cu^(2+)` ions at equilibrium ?
