1.	`Fe^(2+) (aq)+NO_(3)^(-) (aq)+H_(2)SO_(4) (conc.) to` Brown ring The brown ring is due to the formation of complex, `[Fe(H_(2)O)_(5)NO]SO_(4)`. What is the oxidation state of iron in the complex ?
Answer» Correct Answer - 1 Here `NO` is `NO^(+)`, so in `[Fe(H_(2)O)_(5)NO^(+)]^(2+)`, the oxidation state of iron is `+1`
