Iron cyanide bonds
WebAs indicated in Table 35.10, the iron–cyanide precipitation process is capable of achieving relatively low levels of total cyanide at pH 7.0 and an Fe:CN molar ratio of about 4:1 ( … Cyanide is basic. The pKa of hydrogen cyanide is 9.21. Thus, addition of acids stronger than hydrogen cyanide to solutions of cyanide salts releases hydrogen cyanide. Cyanide is unstable in water, but the reaction is slow until about 170 °C. It undergoes hydrolysis to give ammonia and formate, which are far less toxic than cyanide: CN + 2 H2O → HCO−2 + NH3
