Question

The following reactions take place in the blast furnace in the preparation of impure iron. Identify the reaction pertaining to the formation of the slag.

F e_{2} O_{3} (s) + 3 CO (g) ⟶ 2 F e (l) + 3 C O_{2} (g)

C a C O_{3} (s) ⟶ C a O (s) + C O_{2} (g)

C a O (s) + S i O_{2} (s) ⟶ C a S i O_{3} (s)

2 C (s) + O_{2} (g) ⟶ 2 CO (g)

In the blast furnace, during the preparation of impure iron, slag is obtained by the reaction of

C a O

with silica.

Slag can be defined as a fusible mass, which is obtained when a flux reacts with an infusible acidic or basic impurity present in the oxide ore.

C a O (s)

(basic flux)

+ S i O_{2} (s)

(acidic flux)

⟶ C a S i O_{3} (s)

(slag)
