Question

Match the anionic species given in Column I that are present in the ore(s) given in Column II.
$\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{(A) Carbonate}& \text{(P) Siderite}\\ \text{(B) Sulphide}& \text{(Q) Malachite}\\ \text{(C) Hydroxide}& \text{(R) Bauxite}\\ \text{(D) Oxide}& \text{(S) Calamine}\\ & \text{(T) Argentite}\end{array}$

• A. $A\to P,Q,S;B\to T;C\to Q,R;D\to R$
• B. $A\to P,S;B\to Q;C\to Q,T;D\to P$
• C. $A\to Q,S;B\to S;C\to Q;D\to P$
• D. $A\to P,Q;B\to R;C\to Q,R;D\to T$

Answer 1

The correct option is A $A\to P,Q,S;B\to T;C\to Q,R;D\to R$

$\text{(P) Siderite}-FeC{O}_3$
$\text{(Q) Malachite}-CuC{O}_3.Cu(OH{)}_2$
$\text{(R) Bauxite}-Al{O}_x(OH{)}_{3-2x}$
$\text{(S) Calamine}-ZnC{O}_3$
$\text{(T) Argentite}-A{g}_{2}S$
