Question

Match List-I will List-II:

	List-I  Solid salt treated with dil. \(H_2SO_4\)		List-II Anion detected
A.	effervescence of colourless gas	I.	\(NO ^{-}_2\)
B.	gas with smell of rotten egg	II.	\(CO ^{2-}_3\)
C.	gas with pungent smell	III.	\(S^{2-}\)
D.	brown fumes	IV.	\(SO ^{2-}_3\)

Choose the correct answer from the options given below: 

(1) A-II, B-III, C-IV, D-I 

(2) A-IV, B-III, C-II, D-I 

(3) A-I, B-II, C-III, D-IV 

(4) A-II, B-III, C-I, D-IV

Answer 1

Correct option is (1) A-II, B-III, C-IV, D-I 

	Anion	Observation on treatment with dil. \(H_2 SO _4\)
(A)	Carbonate \((CO^{2-}_3)\)	Brisk effervescence of colourless and odourless gas \((CO_2)\)
(B)	Sulphide \((S^{2-})\)	Evolution of colourless gas with rotten egg like smell \((H_2S)\)
(C)	Sulphite \((SO ^{2-}_3)\)	Gas with pungent smell \((SO_2)\)
(D)	Nitrite \((NO ^-_2)\)	Brown fumes \((NO_2)\)
