Question

Match List-I with List-II :

List - I(Test/reagent)	List - II(Radical identified)
(A) Lake Test	(I) NO3−
(B) Nessler’s Reagent	(II) Fe3+
(C) Potassium sulphocyanide	(III) Al3+
(D) Brown Ring Test	(IV) NH4+

Identify the correct answer from the options given below :

• A. A-IV, B-II, C-III, D-I
• B. A-II, B-IV, C-III, D-I
• C. A-II, B-III, C-IV, D-I
• D. A-III, B-IV, C-II, D-I

Answer 1

The Correct Option is D

A-III: Lake test identifies Al$^{3+}$ ions.
B-IV: Nessler's reagent detects NH$_4^+$ ions.
C-II: Potassium sulphocyanide identifies Fe$^{3+}$ ions.
D-I: Brown ring test identifies NO$_3^-$ ions.
The correct matching is: A-III, B-IV, C-II, D-I, corresponding to option (4).
