Text Solution

AI Generated Solution

To calculate the EMF of the concentration cell `Zn|ZnSO4(0.05M)||ZnSO4(0.5M)|Zn` at 298 K, we will follow these steps: ### Step 1: Identify the Anode and Cathode In a concentration cell, the side with the lower concentration acts as the anode, and the side with the higher concentration acts as the cathode. Here: - Anode: `Zn|ZnSO4(0.05M)` - Cathode: `Zn|ZnSO4(0.5M)` ### Step 2: Write the Half-Reactions ...
