Match the anionic species given in Column I that are present in the ore(s) given in Column II.

Column I	Column II
(A) Carbonate	(P) Siderite
(B) Sulphide	(Q) Malachite
(C) Hydroxide	(R) Bauxite
(D) Oxide	(S) Calamine
	(T) Argentite

Answer: A → I, A → II, A → IV, B → V, C → II, C → III, D → III

Solution

Matching anionic species with ores:

(A) Carbonate matches:

(P) Siderite: $FeCO_{3}$
(Q) Malachite: $CuCO_{3} \cdot Cu (OH)_{2}$
(S) Calamine: $ZnCO_{3}$

(B) Sulphide matches:

(T) Argentite: $Ag_{2} S$

(C) Hydroxide matches:

(Q) Malachite: $CuCO_{3} \cdot Cu (OH)_{2}$
(R) Bauxite: $Al_{2} O_{3} \cdot 2 H_{2} O$ or $Al (OH)_{3}$

(D) Oxide matches:

(R) Bauxite: $Al_{2} O_{3} \cdot 2 H_{2} O$
