Question:

Mischmetall consists of

Options:

Lanthanoid metal (~95%), Iron (~5%), traces of S, C, Ca and Al

Lanthanoid metal (~85%), Iron (~15%), traces of S, C, Ca and AI

Actinoid metal (~90%), Iron (~10%), traces of S, C, Ca and Al

Actinoid metal (~95%), Iron (~3%), traces of C, Ca and A

Correct Answer:

Lanthanoid metal (~95%), Iron (~5%), traces of S, C, Ca and Al

Explanation:

The correct answer is Option (1) → Lanthanoid metal (~95%), Iron (~5%), traces of S, C, Ca and Al

Mischmetall is an alloy mainly composed of lanthanoid (rare earth) metals with iron and small impurities.

Its typical composition is:

  • Lanthanoid metals ≈ 95%
  • Iron ≈ 5%
  • Traces of S, C, Ca and Al

So Correct answer: Lanthanoid metal (~95%), Iron (~5%), traces of S, C, Ca and Al
