The reducing agent which is used to reduce iron oxide in blast furnace is
- A \(\mathrm{CO}\)
- B coke
- C silica
- D lime
Answer & Solution
Correct Answer
(A) \(\mathrm{CO}\)
Step-by-step Solution
Detailed explanation
In the blast furnace, iron oxides such as \(\mathrm{Fe_2O_3}\) are reduced to metallic iron. The process involves two main reducing agents: coke (\(\mathrm{C}\)) and carbon monoxide (\(\mathrm{CO}\)). Coke acts as the primary fuel and also reacts with oxygen to form…
