What is a reversible galvanic cell? Why is the Nemst equation insufficient to determine the emf of a Daniel cell?
A reversible galvanic cell has two electrodes which has capable of conducting electricity and a reaction medium, a liquid solution or a solid solution of an electrolyte.
Gases, solids and liquids participating in the cellreaction may be in contact with the electrodes and solution.
