Vedclass · Answer

(C) The correct matches are as follows:$(A)$ Zone refining is used for the purification of semiconductors like $Ga, Si, Ge$. Thus,$A \rightarrow III$.$(B)$ Poling is used for the purification of copper $(Cu)$ containing $Cu_2O$ as an impurity. Thus,$B \rightarrow IV$.$(C)$ Liquation is used for metals with low melting points like tin $(Sn)$. Thus,$C \rightarrow II$.$(D)$ Vapour phase refining is used for metals like $Ti$ and $Zr$ (Van Arkel method) or $Ni$ (Mond process). Thus,$D \rightarrow I$.Therefore,the correct matching is $A-III, B-IV, C-II, D-I$.
