| 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 | Notclassified |
| Safety Profile | Mildly toxic by ingestion. An experimental teratogen. When heated to decomposition it emits toxic fumes of NOx. |
