WebAug 4, 2014 · Ammonium cyanide, N H X 4 C N, is a solid where the atoms are grouped into the same ions that are generated in solution: N H X 4 X + and C N X −. Although it can be sublimed with very mild warming, it is fairly unstable. In particular it reacts with atmospheric water vapor, evolving ammonia and HCN. Dangerous stuff! WebThe correct order of Ka for the hydrolysis reaction of each acid is: B) Ka (HNO3) < Ka (HF) < Ka (CH 3COOH) < Ka (HCN) This is because the order of Ka values reflects the relative strength of the acids. In general, the stronger the acid, the weaker its conjugate base, and the more likely it is to undergo hydrolysis.
