Question

Assertion (A): Sponge iron is called Direct Reduced Iron.

Reason (R): Sponge iron is made by directly reducing iron ore into iron using carbon, and its surface has a number of holes.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (А).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is true but (R) is false.

• (A) is false but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (А).

Explanation:

Sponge iron is called Direct Reduced Iron because it is produced by reducing iron ore directly in its solid state using carbon or reducing gases. The removal of chemically bound oxygen creates micropores throughout the ore, leaving behind a porous, sponge-like structure.
