1.

(a) Give one example each of the following: (i) Acidic flux(ii) Basic flux (b) What happens when (i) Cu_2 O undergoes self reduction in a silica line converter (ii) Haematite oxidises carbon to carbon monoxide.

Answer»

Solution :(a) (i) ACIDIC flux : `SiO_2 "" (ii) ` Basic flux : `CaO`
(b) (i) `Cu_2 O ` undergoes SELF REDUCTION to form BLISTER copper as :
`2Cu_2 O + Cu_2 S to underset("Blister copper")(6Cu) + SO_2`
(ii) Haematite oxidises carbon to carbon monoxide forming IRON .
`Fe_2 O_3 + 3C to 3CO + 2Fe`
