Question:

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

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

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

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

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

Solution:

Solution:- (D) (I) - (c); (II) - (d); (III) - (b); (IV) - (a)
Liquation is used for Sn.
Zone refining is used for Ga.
Mond's process is used for Ni.
Van arkel process is used for Zr.
