What happens when E ext is greater than 1.1 V in a Daniell cell?

Options

  1. AElectrons flow from Zn to Cu, and current flows from Cu to Zn.
  2. BElectrons flow from Cu to Zn, and current flows from Zn to Cu.
  3. CZn dissolves at anode, and copper deposits at cathode.
  4. DCopper dissolves at anode, and Zn deposits at cathode.

Correct answer

A. Electrons flow from Zn to Cu, and current flows from Cu to Zn.

Step-by-step solution

When Eext is greater than 1.1 V, electrons flow from Cu to Zn, and current flows from Zn to Cu.
