| | Tetrapotassium hexacyanoferrate trihydrate Usage And Synthesis |
| Chemical Properties | Also known as yellow prussiate of potash, K4Fe(CN)6.3H20 is yellow crystals with a saline taste that are soluble in water,insoluble in alcohol and loses water at 60°C. Used in medicine,dry colors,explosives, and as an analytical reagent.
| | Chemical Properties | Lemon-yellow crystals or powder; mild
saline taste.
Effloresces on exposure to air; soluble in water;
insoluble in alcohol. | | Uses | Potassium cyanide and ferricyanide, dry colors,
tempering steel, dyeing, explosives, process engrav-
ing and lithography, laboratory reagent. | | Production Methods | Potassium ferrocyanide is used as a chemical reagent, in
metallurgy, and in graphic arts. | | Hazard | It evolves highly toxic fumes on heating to
red heat, but the compound itself has low toxicity. | | Flammability and Explosibility | Not classified | | Safety Profile | Mildly toxic by ingestion. An experimental teratogen. When heated to decomposition it emits toxic fumes of NOx. |
