Testing for ferrous ions with potassium ferricyanide
The ability for potassium ferricyanide to be used to test for ferrous ions. In industrial environments it is used to determine if free metal ions are present on steel or other iron surfaces which lead to rusting.
Potassium ferricyanide for use in photography
Potassium ferricyanide is widely used as a chemical reducer in photographic processing to remove silver from negatives and positives (dot etching). This is done to compensate for minor errors in a photograph or to make deliberate changes in the reproduction. In coluor reproduction of photographs, potassium ferricyanide is used to reduce the size of dots on halftone positives without reducing their density and, thereby, reducing the amount of color in treated areas. This is the most important means of manual colour correction of original color photographs.
Other uses for Potassium ferricyanide
Potassium ferricyanide is also used in tempering iron and steel, sensitive coatings on blueprint paper, wood staining, dyeing wool, production of pigments, electroplating, as a laboratory reagent, and a mild oxidizing agent in organic synthesis.
In the laboratory potassium ferricyanide is used to produce the ferricyanites of heavy metals including mercury, silver, copper, iron 2+ and iron 3+.
