Doing the Brown Ring Test
Mix freshly made ferrous sulphate solution with the test solution, then run concentrated sulphuric acid slowly down the side of the tilted tube so that it settles as a layer underneath. A brown ring where the two layers meet shows a nitrate: Fe2+ reduces nitrate to nitric oxide, which then joins another Fe2+ ion as the brown complex [Fe(H2O)5NO]2+.
Iron(II) in Solution
Air slowly oxidises Fe2+ to Fe3+, which is why the solution is made shortly before use. Sodium hydroxide gives a dirty green precipitate of iron(II) hydroxide, and potassium ferricyanide a dark blue one.
