 P: 86 1. The problem statement, all variables and given/known data 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??? 2. Relevant equations NO2-(aq) + FeSO4(aq) + CH3COOH(aq)$\Rightarrow$ [A Brown Circle]??? or is this equation invalid??? 3. The attempt at a solution Nothing being attempted!!! :(
