Question
![**Understanding Galvanic Cells**
The image illustrates the components and functioning of a galvanic cell, also known as a voltaic cell. A galvanic cell generates electrical energy through spontaneous redox reactions.
### Components of the Galvanic Cell
1. **Electrodes**: Solid conductors through which electrical current enters or leaves an electrochemical cell.
- **Anode (A)**: The electrode where oxidation occurs, releasing electrons.
- **Cathode (E)**: The electrode where reduction occurs, accepting electrons.
2. **Salt Bridge (C)**: A pathway constructed to allow the transfer of ions while preventing the solutions in the two half-cells from mixing directly. It completes the circuit and maintains electrical neutrality.
3. **Solutions (B and D)**: These beakers contain the ionic solutions in which the respective redox reactions occur.
The diagram includes:
- **A Voltmeter**: Used to measure the potential difference between the two electrodes.
- **Direction of Electron Flow**: Electrons flow from the anode to the cathode through the external circuit (depicted by the connecting wires and voltmeter).
### Questions to Test Understanding
Identify the following components:
(a) **Anode**
(b) **Cathode**
(c) **Salt Bridge**
(d) **Electrode at which electrons (\(e^-\)) leave the cell**
(e) **Electrode with a positive charge** (assuming electrons (\(e^-\)) are moving clockwise in the diagram)
(f) **Electrode that gains mass as the cell operates** (assuming that a metal plates out)
