2081 AshwinChapter 1: Electrochemistry and Buffer1.1.2 EMF of Galvanic Cell, Nernst Equation
The standard reduction potentials of Cd2+/Cd and Ni2+/Ni electrodes are −0.403 V and −0.25 V respectively. Construct a galvanic cell using these electrodes so the standard emf of the cell becomes positive. For what concentration of Cd does the emf of the cell at 25°C become zero, if the concentration of Ni is 0.01 M?
