Question

Transcribed Image Text:**Question:**
All of the following statements concerning voltaic cells are true *except*:
- A voltaic cell consists of two-half cells.
- Electrons flow from the cathode to the anode in the external circuit.
- Oxidation occurs at the anode.
- A salt bridge allows electrons to move between the half-cells.
- A voltaic cell can be used as a source of energy.
**Note:**
Voltaic cells, also known as galvanic cells, are electrochemical cells that derive electrical energy from spontaneous redox reactions taking place within the cell. They consist of two half-cells, each containing an electrode and an electrolyte, connected by a salt bridge. Electrons flow from the anode to the cathode through an external circuit, enabling the cell to act as a power source.
