Question

The difference of potential of two electrodes in a galvanic cell is known as:

• A. EMF
• B. Potential difference
• C. Electrode difference
• D. Ionic difference

Answer 1

The correct option is C Electrode difference

Electrode potential is the electrode potential on an electrode component. In a cell, there is an electrode potential for the cathode and an electrode potential for the anode.

The difference in between these two cathode electric potential and anode electrode potential equals to the cell potential

$E_{cell}=E_{cathode}-E_{anode}$.

$\Rightarrow$ The difference of potential of two electrodes in a galvanic cell is known as electrode difference.
