Potassium Ferricyanide
Potassium Ferricyanide is also known as red prussiate, prussian red or potassium hexacyanoferrate(III). It is a coordination compound that is stable at room temperature and pressure and forms ruby red crystals and powder. It is soluble in water and its solution shows some green-yellow fluorescence. The compound has widespread use in blueprint drawing and in photography. Iron and copper toning involve the use of potassium ferricyanide. Potassium ferricyanide is used as an oxidising agent to remove silver from negatives and positives, a process called dot etching. The compound is also used to temper iron and steel, in electroplating, dyeing wool, as a laboratory reagent, and as a mild oxidising agent in organic chemistry. Grades: Technical. Chemical formula: K3[Fe(CN)6]. Pack Sizes: MOQ is 1 pallet/1mt - We don't supply small quantities, Norkem supply bulk order quantities with CIF delivery- Norkem your first link in the chemical chain.
