Oxidation of an aniline salt by means of a solution of ferricyanide of potassium.Cooley's Practical Receipts, Volume II|Arnold Cooley
The first of these is the bleach, or oxidizing mixture of bromide and ferricyanide.
Ferricyanide of potassium gives a blue precipitate or green coloration; with ferric salts a brown colour only is produced.
The ferricyanide-bromide mixture, however, keeps very much better than a plain solution of ferricyanide alone.
