SATHEE: General Principles and Processes of Isolation of Elements

General Principles and Processes of Isolation of Elements - Result Question 12

####12. 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.

[2011 M]

(a) $F e_{2} O_{3} (s) + 3 C O (g) \to 2 F e (l) + 3 C O_{2}$ (g)

(b) $C a C O_{3} (s) \to C a O$ (s) $+ C O_{2} (g)$

(d) $2 C (s) + O_{2} (g) \to 2 C O (g)$

Show Answer

Solution:

(c) In blast furnace at about $1270 K$ , calcium carbonate is almost completely decomposed to give $C a O$ which acts as a flux and combines with $S i O_{2}$ present as impurity (gangue) in the ore to form calcium silicate (fusible slag)

$C a O$ (s) (basic flux) $+ S i O_{2}$ (s) (acidic flux)

$⟶ C a S i O_{3}$ (s) (slag)
