How aluminium is extracted using electrolysis
Did you know?
WebQ1: Aluminium is usually extracted by the electrolysis of aluminium oxide (AlO)23. Before it can be electrolyzed, aluminium oxide must be melted. However, aluminium oxide has a melting point greater than 2,000 " which is very expensive to maintain. What is added to reduce the melting point of aluminium oxide before electrolysis? Web10 de jul. de 2024 · As you will see if you read the page about titanium extraction, this is the only way of producing high purity metal. (1) T i C l 4 + 4 N a → T i + 4 N a C l. The more reactive metal sodium releases electrons easily as it forms its ions: (2) 4 N a → 4 N a + + 4 e −. These electrons are used to reduce the titanium (IV) chloride: (3) T i C l ...
