An Introduction to the Chemistry of Metal Extraction

 · 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 4 + 4 e − → T i + 4 C l −. The downside of this is expense. You have first to extract (or to buy) the sodium or magnesium.
