Chemistry - Metallurgy Question with Solution | TestHub

Statement-I is True because coke is added in the blast furnace during the extraction of iron. Coke acts as a fuel and also produces CO, which reduces iron oxides to iron.

Statement-II is False because in the commercial extraction of copper, Cu₂O is reduced by Cu₂S (self-reduction), not by coke reducing CuO directly.

Therefore, Statement-I is true and Statement-II is false.

$$2C{u}_{2}O+C{u}_{2}S\to 6Cu+S{O}_2$$
