Question

The transition element ( ≈ 5%) present with lanthanoid metal in Misch metal is:

• A. Mg
• B. Fe
• C. Zn
• D. Co

Answer 1

The Correct Option is B

Misch metal is an alloy consisting mostly of the lanthanoid metals (rare earth elements), along with small amounts of other elements. The transition element commonly present (approximately 5%) with lanthanoids in Misch metal is iron (Fe).

• Misch metal is primarily used in making lighter flints and for certain types of alloys.
• It typically contains about 95% lanthanoids, mainly cerium (Ce), and small amounts of other elements, like iron (Fe) and sometimes magnesium (Mg).

Thus, the transition element iron (Fe) is present in Misch metal, making the correct answer (B).
