🔬 Example: Electrolysis of Molten Lead Bromide (PbBr₂)

🔵 CATHODE (−)

🪨

Pb²⁺ + 2e⁻ → Pb

Product: Lead metal

(Silvery liquid, sinks to bottom)

🔴 ANODE (+)

💨

2Br⁻ → Br₂ + 2e⁻

Product: Bromine gas

(Orange/brown fumes)

Overall: PbBr₂ → Pb + Br₂

The compound is broken down into its elements using electrical energy
