ferricyanide

[ fer-ahy-sahy-uh-nahyd, fer-ee- ]

/ ˌfɛr aɪˈsaɪ əˌnaɪd, ˌfɛr i- /

a salt of ferricyanic acid, as potassium ferricyanide, K3Fe(CN)6.

Origin of ferricyanide

First recorded in 1865–70; ferri- + cyanide

The ferricyanide had a small influence and, as might be expected, hyposulphite is fatal to the assay.

Oxidation of an aniline salt by means of a solution of ferricyanide of potassium.

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.
