Question
The image illustrates the electrolysis of molten lead(II) chloride (PbCl₂). The diagram features the following components:

1. **Voltage Source**: Positioned at the top, supplying electrical energy to the system.
2. **Anode (Left Side)**: This electrode is connected to the positive terminal of the voltage source. Electrons are shown moving away from the anode towards the cathode.
3. **Cathode (Right Side)**: Connected to the negative terminal, electrons move towards this electrode.
4. **Porous Screen**: Located between the anode and cathode, likely serving to separate the products formed during electrolysis.
5. **Molten PbCl₂**: The electrolyte in which the electrolysis occurs, represented as the medium filling the container.

The diagram implies that at the anode, chloride ions (Cl⁻) lose electrons and form chlorine gas, while at the cathode, lead ions (Pb²⁺) gain electrons to form lead metal.

**Electrolysis of Molten Lead(II) Chloride (PbCl₂)**

To determine the minimum voltage required for electrolysis to occur in a cell containing molten PbCl₂, it is crucial to understand the breakdown of this compound during the electrolysis process.

**Text:**
"Determine the minimum voltage that must be applied to a cell containing molten PbCl₂ in order for electrolysis to occur."
- [ ] V (Input box for the voltage value)

**Explanation:**
Electrolysis involves driving a non-spontaneous chemical reaction with electricity. For molten PbCl₂, the electrolytic process will result in the decomposition of PbCl₂ into lead (Pb) and chlorine gas (Cl₂). The minimum voltage required, also known as the decomposition potential, depends on the half-reactions at the electrodes and their standard electrode potentials. By summing the potentials of the oxidation and reduction half-reactions, one can calculate the minimum voltage necessary for the electrolysis of molten PbCl₂ to proceed.
