Question: Match the refining methods (Column I) with metals (Column II).
(I) $-(\mathrm{b}) ;(\mathrm{II})-(\mathrm{c}) ;(\mathrm{III})-(\mathrm{d}) ;(\mathrm{IV})-(\mathrm{a})$
(I) $-(\mathrm{b}) ;(\mathrm{II})-(\mathrm{d}) ;(\mathrm{III})-(\mathrm{a}) ;(\mathrm{IV})-(\mathrm{c})$
$(\mathrm{I})-(\mathrm{c}) ;(\mathrm{II})-(\mathrm{a}) ;(\mathrm{III})-(\mathrm{b}) ;(\mathrm{IV})-(\mathrm{d})$
$(\mathrm{I})-(\mathrm{c}) ;(\mathrm{II})-(\mathrm{d}) ;(\mathrm{III})-(\mathrm{b}) ;(\mathrm{IV})-(\mathrm{a})$
Correct Option: , 4
Solution:
Liquation is used for Sn.
Zone refining is used for Ga.
Mond's process is used for $\mathrm{Ni}$.
Van arkel process is used for $\mathrm{Zr}$.
