Potassium Ferricyanide

Uses and Purposes:Potassium Ferricyanide is used for blue prints and is used in black in white photos to brighten the highlights of the prints and photos. Another use in Photoigraphy is it's used in reducing overexposure to pictures. It's also combined in certain solutions that can detect metal oxidation that will eventually lead to rust

Interesting factsPotassium ferricyanide decomposes at it's boiling point meaning that when it reaches boiling point thermal decomposition, or thermolysis, a chemical decomposition caused by heat begins. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive feedback loop is created producing thermal runaway and possibly an explosion.

3 Physical and 3 Chemical PropertiesPhysical:1) It is a red/orange color2) 300 °C; 572 °F; 573 K3)slightly soluble in alcohol soluble in acid soluble in waterChemical:1) Low toxicity2) under very strongly acidic conditions, highly toxic hydrogen cyanide gas is evolved3) Addition of metal chlorates, perchlorates, nitrates, or nitrites to a solution of carefully prepared and otherwise stable potassium ferrocyanide may result in a large explosion.

Step 1: Start!

Fira the FairyBy: Kameyo OkamotoI named my mole after the disney fairy Fira because fira the fairy likes to make pictures with her light magic and Potassium Ferricyanide is used to reduce the sizes of colored dots in photos!

Step 2: Sew!!

Step 3: Tada!!!
