Electrolysis of aluminium oxide chemical equation
Explain, with the help of a half equation. Aluminium oxide (Al2O3) is an ionic compound. The ions in the aluminium oxide must be free to move so that electricity can pass through it.
Extracting metals using electrolysis – What are electrolytes and what. Aluminum is extracted from aluminum oxide by a process called electrolysis. The steel case, used in electrolysis, is coated by graphite.
