Question

In the extraction of iron, carbon monoxide acts as O A catalyst OB an inert gas . an oxidising agent . a reducing agent .

Answer 1

a reducing agent .

Step-by-step explanation:

In the extraction of iron, carbon monoxide acts as the main reducing agent.

Carbon monoxide is a neutral, colorless and odorless gas. One of the property of carbon monoxide is that it is a powerful reducing agent as it combines with oxygen readily to form CO₂ and hence its use in metallurgy.

• A reducing agent is one that undergoes oxidation in a chemical process.
• The carbon monoxide is produced in the furnace at high temperature.
• Carbon dioxide combines with carbon to produce carbon monoxide.

So, carbon monoxide acts as the main reducing agent.
