I know that NO3- can be separately identify using newly made FeSO4 + H2SO4 using the brown ring test.
The problem is can we identify NO2- using newly made FeSO4 + CH3COOH??? Replacing H2SO4 with CH3COOH???
NO2-(aq) + FeSO4(aq) + CH3COOH(aq)[itex]\Rightarrow[/itex] [A Brown Circle]???
or is this equation invalid???
The Attempt at a Solution
Nothing being attempted!!! :(
