    en.wikipedia.org/wiki/Nitrate_test

    A common nitrate test, known as the brown ring test[ 2 ] can be performed by adding iron (II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [ 3 ]

    Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al 3+ is small and highly charged; as such, it has more polarizing power, and bonds formed by aluminium have a more covalent character.
