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

Web13 nov. 2024 · Similarly, the CN – ion binds strongly to a proton, making HCN a weak acid. Salts of weak acids give alkaline solutions The fact that HCN is a weak acid implies that the cyanide ion CN – reacts readily with protons, and is thus is a relatively good base. notting hill residence by egali
