What is the difference between ferricyanide and ferrocyanide

This compound can be identified as the potassium salt of the ferrocyanide coordination complex. Therefore, potassium is the cation in this complex while iron-cyanide complex is the anion.

This substance occurs as monoclinic crystals having a lemon-yellow color. The modern production method for potassium ferrocyanide includes the industrial technique, which involves the chemical compounds HCl, FeCl2, and Ca OH 2.

The combination of these chemical substances forms a solution which is then treated with potassium salt in order to get the precipitated form of calcium-potassium salt having the chemical formula CaK2[Fe CN 6].

Thereafter, we need to treat this resulting solution with potassium carbonate in order to get the tetrapotassium salt. There are different important uses of potassium ferrocyanide, including the use of this compound as anticaking agents for both road salt and table salt, in the purification of tin and the separation of copper from molybdenum ores, in the production of wine and citric acid, etc.

Potassium ferrocyanide compound can be recognized as a non-toxic compound which does not decompose to form cyanide in the body. Potassium ferricyanide is an inorganic compound having the chemical formula K3[Fe CN 6]. It is a bright red colored salt that contains an octahedrally coordinated iron-cyanide complex anion.

Willows grown in the N-containing nutrient solution showed a higher assimilation potential for both chemical forms than those grown in the N-free nutrient solution in general. The information collectively suggests that uptake and assimilation mechanisms for ferro- and ferricyanide are largely different in willows; the strength of external nitrogen had a negligible effect on the uptake of both chemicals, while assimilation of ferro- and ferricyanide in plant materials was strongly related to the presence of easily available nitrogen in the hydroponic solution.

Abstract The effects of different levels of external nitrogen on the uptake, distribution and assimilation of iron cyanide complexes were investigated.
