concentration cell

Question

A concentration cell is formed when:

RankGuru · Accepted Answer

A **Concentration Cell** is a unique electrochemical cell where the two half-cells are chemically identical but have different concentrations of the electrolyte.
- Structure: Both the anode and cathode are made of the **same metal** immersed in solutions of the **same salt** but at different concentrations ($C_1$ and $C_2$).
- **EMF ($E_{cell}$)**: Driven purely by the entropy of dilution. The standard cell potential ($E^\circ$) is zero because the electrodes are identical. 
- Reaction occurs as ions move from higher concentration to lower concentration symbolically through electron flow.
