Question

The standard reduction potential of Cu²⁺/Cu and AG⁺/AG electrodes are 0.337 and 0.799V respectively. construct a galvanic cell using these electrodes so that its standard emf is positive. For what concentration of Ag⁺ will the emf of the cell, al 25°C, be zero if the concentration of Cu²⁺ is 0.01M.

Answer 1

Cu should be oxidized and Ag⁺ is reduced because
