In pH 1.0 acidic medium, double‐charged triaminotriphenylmethane dyes such as methyl green (MeG) and iodine green (IG) react with potassium ferrocyanide to form 2:1 ion‐association complexes by virtue of electrostatic forces and hydrophobic interaction. ferrocyanide. The ferrocyanide species is membrane impermeable, which means that no substance can pass through this material. This salt forms lemon-yellow monoclinic crystals. In the extreme case, cooking temperatures generally do not exceed 340 degrees Celsius.Suppose one day, when someone is cooking, all the potassium ferrocyanide in the salt is magically decomposed and potassium cyanide is produced. However, the excess of K 4 [Fe(CN) 6 ] and its decomposers are harmful to both human health and environment. In the extreme case, cooking temperatures generally do not exceed 340 degrees Celsius.
