In the Zn - Cu cell, standard reduction potential of Zn=-0.763 volt. Standard reduction potential of Cu=0.335 volt. Name the cathode and anode in this electrochemical cell.

Explanation

To determine the cathode and anode in the Zn-Cu electrochemical cell, we can follow these steps:

### Step 1: Understand the Standard Reduction Potentials
- We have the standard reduction potentials for both zinc (Zn) and copper (Cu):
- Standard reduction potential of Zn = -0.763 V
- Standard reduction potential of Cu = +0.335 V

### Step 2: Compare the Standard Reduction Potentials
- In an electrochemical cell, the electrode with the higher standard reduction potential will act as the cathode, while the electrode with the lower standard reduction potential will act as the anode.
- Here, +0.335 V (Cu) is greater than -0.763 V (Zn).

### Step 3: Identify the Cathode and Anode
- Since Cu has a higher standard reduction potential, it will act as the cathode.
- Conversely, Zn, having a lower standard reduction potential, will act as the anode.

### Conclusion
- **Cathode**: Copper (Cu)
- **Anode**: Zinc (Zn)
