Question

Explain concentration cell.

✓

Answer

The cell in which two identical electrodes are immersed in solutions with different concentration of their ions. Due to this, the potential of these electrodes also varies. Therefore the potential is produced in the cell. The cell potential at 298 K is $E _{\text {cell }}=\frac{0.059}{ n } \log \frac{ C _2}{ C _1}$
$C _1=$ concentration of anode, $C _2=$ concentration of cathode
Here $\left( C _1< C _2\right)$.
