Question

Match the following.

List I		List II
A	Feldspar	I	$\left[ Ag _{3} SbS _{3}\right]$
B	Asbestos	II	$Al _{2} O _{3} \cdot H _{2} O$
C	Pyrargyrite	III	$MgSO _{4} \cdot H _{2} O$
D	Diaspore	IV	$KAlSi _{3} O _{8}$
		V	$CaMg _{3}\left( SiO _{3}\right)_{4}$

The correct answer is

• A. $A \to IV, B \to V, C \to II, D \to I$
• B. $A \to IV, B \to V, C \to I, D \to II$
• C. $A \to IV, B \to I, C \to III, D \to II$
• D. $A \to II, B \to V, C \to IV, D \to I$

Answer 1

Answer: (B)

(A) Feldspar (orthoclase) $\left( KAlSi _{3} O _{8}\right)$ It is used in the manufacture of porcelain.

(B) Asbestos $\left\{ CaMg _{3}\left( SiO _{3}\right)_{4}\right\}$ It is used for fireproof sheets, cloths etc.

(C) Pyrargyrite (Ruby silver) $\left( Ag _{3} SbS _{3}\right)$ It is an ore of silver.

(D) Diaspore $\left( Al _{2} O _{3} \cdot H _{2} O \right)$ It is an ore of aluminium.
