Potassium Ferricyanide AR 500g
Potassium ferricyanide (K3[Fe(CN)6]) is a versatile reagent used in various laboratory applications. It acts as an oxidizing agent, a reagent for detecting ferrous iron, and a component in several analytical tests. It's also used in the production of pigments, electroplating, and as a component in blueprinting and photography (cyanotype process).
Here's a more detailed Potassium Ferricyanide AR 500g breakdown of its uses:
1. Histology and Biological Analysis:
Ferrous Iron Detection: Potassium ferricyanide reacts with ferrous iron (Fe2+) in biological tissue to produce a blue precipitate, commonly known as Turnbull's blue or Prussian blue. This reaction is used in histology to visualize and identify the presence of ferrous iron in tissue samples.
2. Analytical Chemistry:
Reagent and Indicator:
Potassium ferricyanide is used as a reagent in various analytical tests, including the detection of certain sugars, nitrite ions, thiourea, and various metals.
Oxidizing Agent:
It acts as an oxidizing agent in the preparation of diethidium and di-mito-ethidium and in the fabrication of glucose conductometric biosensors.
Quantitative Analysis:
Potassium ferrocyanide, which is closely related to potassium ferricyanide, is used in the quantitative determination of metals like zinc, cadmium, cerous ions, and lead.
3. Industrial Applications:
Pigment Production: Potassium ferricyanide is a key component in the production of Prussian blue pigment.
Electroplating: It is used in electroplating processes.
Dyeing Wool: Potassium ferricyanide is used in the dyeing of wool.
Tempering Iron and Steel: It is used in the process of hardening iron and steel.
4. Photography and Blueprinting:
Cyanotype Process: Potassium ferricyanide is a crucial ingredient in the cyanotype process, a photographic printing method that produces cyan-blue images.
5. Other Uses:
Laboratory Reagent: It is a common reagent in various laboratory procedures and experiments.
Mild Oxidizing Agent: Potassium ferricyanide can be used as a mild oxidizing agent in certain organic reactions.
Ferroxyl Indicator: It is one of the components in a ferroxyl indicator solution used to detect metal oxidation (rust).
Important Note: Potassium ferricyanide decomposes under certain conditions, such as when heated or in contact with acids, releasing toxic cyanide fumes. Therefore, it should be handled with care and appropriate safety precautions should be followed.
In histology, Potassium Ferricyanide AR 500g is used to detect ferrous iron in biological tissue.
It is also initially used in the production of ultramarine dyes
