Brown ring test is a test for HNO3
In this process, in a dilute solution of HNO3 H2SO4 is added with the help of a glass rod.
And also FeSO4 is added.
At the junction of the 2 liquids the brown ring is formed.
Here is its reaction.
HNO3+H2SO4+FeSO4=>Fe2(SO4) 3+H2O+2NO
THEN,
FeSO4+NO=>FeSO4.NO (THIS IS A BROWN COMPOUND, NITROSO FERROUS SULPHATE)
Hope it helped u!

Answer:
A common nitrate test, known as the brown ring test can be performed by adding iron(II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution.
