Practice questions for Electrolysis of Molten Compounds
Which condition is required for electrolysis to occur with an ionic compound?
State the products formed at each electrode when molten lead bromide (PbBr₂) is electrolysed.
Quick recall flashcards
Why does solid lead bromide NOT conduct electricity?
In the solid state, all ions (Pb²⁺ and Br⁻) are held in fixed positions in the ionic lattice by strong electrostatic forces. They cannot move, so they cannot carry electrical charge.
How do you remember that cations go to the cathode?
CATions → CAThode (both start with CAT)
ANions → ANode (both start with AN)
Metal at the Minus (cathode is negative), Non-metal at the Plus (anode is positive).
