🔬 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
