  • question_answer Match the refining methods (Column I) with metals (Column II).
    Column I Column II
    (Refining methods) (Metals)
    (I) Liquation [a] Zr
    (II) Zone Refining [b] Ni
    (III) Mond Process [c] Sn
    (IV) Van Arkel Method [d] Ga
    [JEE Main 10-4-2019 Morning]

    A) \[\left( I \right)\left( b \right);\left( II \right)\left( c \right);\left( III \right)\left( d \right);\left( IV \right)\left( a \right)\]

    B) \[\left( I \right)\left( b \right);\left( II \right)\left( d \right);\left( III \right)\left( a \right);\left( IV \right)\left( c \right)\]

    C) \[\left( I \right)\left( c \right);\left( II \right)\left( a \right);\left( III \right)\left( b \right);\left( IV \right)\left( d \right)\]

    D) \[\left( I \right)\left( c \right);\left( II \right)\left( d \right);\left( III \right)\left( b \right);\left( IV \right)\left( a \right)\]

    Correct Answer: D

    Solution :

    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.
