Ferroxyl, containing potassium ferricyanide, reacts with ferrous ions to produce 'prussian blue' coloration, indicating metal oxidation at the anode. This process occurs in an acidic solution, with the blue pigment being insoluble in water. The reaction serves as a useful indicator for detecting rust and metal oxidation.

Ferroxyl contains the chemical compound Potassium.pdf
- 1. Ferroxyl contains the chemical compound Potassium ferricyanide which reacts with the ferrous ions to produce the color "Prussian blue". Iron is being oxidized at the anode and creating Ferrous (Fe+2) ions. Therefore, with the introduction of Ferroxyl, the anode will turn blue as the Ferroxyl reacts with the Ferrous ions. It is also worth noting that this is a acidic solution and the blue pigment is insoluble in water. This is useful in detecting metal oxidation that leads to rust. Same thing basically for the OH.
