In 1752, the French chemist Pierre Joseph Macquer (1718–1784) first reported the preparation of potassium ferrocyanide, which he achieved by reacting Prussian blue (iron(III) ferrocyanide) with potassium hydroxide. Potassium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca2[Fe(CN)6]·11H2O. This solution is then … Webb25 feb. 2024 · Thus to find the oxidation of Fe, the following calculation must be done: As per the formula of the compound, the oxidation number of and 'CN' is 4 and (-6) respectively. Substituting the value in the following equation: 4 (+1) + x + 6 (-1) = 0 4 + x - 6 = 0 4 - 6 = -x -2 = -x 2 = x Conclusion:
