Acidity regulator Potassium ferrocyanide, also known as yellow prussiate of potash or potassium hexacyanoferrate(II), is a coordination compound of formula K4[Fe(CN)6]?3H2O, which forms lemon-yellow monoclinic crystals at room temperature, and which decomposes at its boiling point.; The reaction forms a stable compound that is neither combustible nor pyrophoric. This compound is a strong reducing agent and is thus incompatible with oxidizing agents. 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.
