Is iron in the brown ring compound in a +1 oxidation state?
WebAnswer: The ‘Brown Ring Test’ is a qualitative test that determines whether nitrate (NO3-) is present. The reaction is: 2 HNO3 + 3 H2SO4 + 6 FeSO4 → 3 Fe2(SO4)3 + 2 NO + 4 H2O [Fe(H2O)6]SO4 + NO = [Fe(H2O)5(NO)]SO4 + H2O So, the compound that makes the brown ring is [Fe(H2O)5(NO)]SO4 Note, thi... WebThe correct formula of the complex formed in the brown ring test for nitrates is: [F e(H 2O)5N O]2+ It is formed through the following reaction: F eS O4 +5H 2O+N O →[F e(H 2O)5N O]S O4 Answer verified by Toppr Upvote (0) Was this answer helpful?
