Question

Pick up the false statement(s):

Options

A.The net chemical change in a galvanic cell reaction is always redox reactions.
B.In a galvanic cell made of copper and cadmium electrodes, cadmium electrode may act as anode.
C.Standard potential increases with increasing concentration of the electrolyte.
D.Calomel electrode is a reference electrode having 0.00 volt potential.

Solution

For the cell: Ag(s)|Ag Cl (s)|Cl−||Ag+|Ag(s), the net cell reaction is Ag+ + Cl− $\rightleftharpoons$AgCl (s).
