Which of the following metals cannot be extracted by the smelting process: Al, Zn, Fe and Pb. Give reason.

Text Solution

Verified by Experts

Aluminium cannot be extracted by smelting process due to the following reasons:
(i) Al being highly electropositive element has very strong affinity for oxygen. So, `Al_(2)O_(3)` is very stable compound and cannot be reduced by C.
(ii) On heating `Al_(2)O_(3)` with C, aluminium carbide is formed.
`2Al_(2)O_(3) + 9C to Al_(4)C_(3) +6CO`
