In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with
Options
(a) carbon monoxide
(b) copper (I) sulphide
(c) sulphure dioxide
(d) iron (II) sulphide
Correct Answer:
copper (I) sulphide
Explanation:
2Cu₂S (s) +3O₂ (g) →2Cu₂O (s) +2SO₂(g)
The unchanged Cu₂S, mixed with Cu₂O and heated strongly in absence of air
2Cu₂S + 2Cu₂O →6Cu +SO₂.
