Match List - I with List - II.

	List - I	List - II
(a)	Siderite	(i) Cu
(b)	Calamine	(ii) Ca
(c)	Malachite	(iii) Fe
(d)	Cryolite	(iv) Al
		(v) Zn

Choose the correct answer from the options given below :

Answer: A → III, B → V, C → I, D → IV

Solution

Siderite is

FeC O_{3}

and is an ore of iron. Calamine is

ZnC O_{3}

and is an ore of zinc. Malachite is the basic carbonate

CuC O_{3} \cdot Cu (OH)_{2}

and is an ore of copper. Cryolite is

N a_{3} Al F_{6}

and belongs to aluminium, where it is used with bauxite in the electrolytic extraction. So siderite pairs with iron, calamine with zinc, malachite with copper and cryolite with aluminium, leaving calcium unmatched.
