Match the refining methods (Column I) with metals (Column II). Column I (Refining methods): (I) Liquation, (II) Zone Refining, (III) Mond Process, (IV) Van Arkel Method Column II (Metals): (a) Zr, (b) Ni, (c) Sn, (d) Ga

1. (I)-(c); (II)-(a); (III)-(b); (IV)-(d)
2. (I)-(c); (II)-(d); (III)-(b); (IV)-(a)
3. (I)-(b); (II)-(d); (III)-(a); (IV)-(c)
4. (I)-(b); (II)-(c); (III)-(d); (IV)-(a)

Correct answer: (I)-(c); (II)-(d); (III)-(b); (IV)-(a)

Solution

Liquation refines low-melting Sn (c); zone refining purifies Ga/semiconductors (d); the Mond process refines Ni (b); the van Arkel method purifies Zr (a). Thus (I)-c, (II)-d, (III)-b, (IV)-a.
