Question
Consider a cell given below $\text{Cu}|\text{Cu}^{2+}||\text{Cl}^{-}|\text{Cl}_2,\text{pt}$ Write the reactions that occur at anode and cathode.
✓
Answer
$\text{Anode}:\ \ \text{Cu}^{-}\xrightarrow{\ \ \ \ \ \ \ \ \ }\text{Cu}^{2+}+2\text{e}^{-}$
$\text{Cathode}:\ \ \text{Cl}_2+2\text{e}^{-}\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }2\text{Cl}^{-}\text{Cu}$ is anode as it is getting oxidised.
Cl2 is cathode as it is getting reduced.
$\text{Cathode}:\ \ \text{Cl}_2+2\text{e}^{-}\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }2\text{Cl}^{-}\text{Cu}$ is anode as it is getting oxidised.
Cl2 is cathode as it is getting reduced.
