Vedclass · Answer

(A) The brown ring test is a common chemical test for the detection of nitrate ions $(NO_3^-)$.When a freshly prepared ferrous sulfate $(FeSO_4)$ solution is added to a solution containing nitrate ions,followed by the careful addition of concentrated sulfuric acid $(H_2SO_4)$ along the sides of the test tube,a brown ring is formed at the interface.The reaction involves the reduction of nitrate to nitric oxide $(NO)$,which then reacts with the hexaaquairon$(II)$ complex to form the brown-colored complex known as pentaaquanitrosyliron$(II)$ sulfate,represented as $[Fe(H_2O)_5NO]SO_4$.

List-$I$ (Conductivity)	List-$II$ (Formula)
$A. \ 229$	$i. \ [Pt(NH_3)_3Cl_3]Cl$
$B. \ 97$	$ii. \ [Pt(NH_3)_4Cl_2]Cl_2$
$C. \ 404$	$iii. \ [Pt(NH_3)_5Cl]Cl_3$
$D. \ 523$	$iv. \ [Pt(NH_3)_6]Cl_4$

The complex formed during the brown ring test of nitrate $(NO_3^-)$ ion is:
