Hydrogen Cyanide - an overview ScienceDirect Topics

WebAt low pH and at neutral pH, hydrogen cyanide is the dominant form of cyanide, and as pH increases CN- becomes the dominant form. At a pH of 11, over 99% of the cyanide remains in solution as CN-, while at pH 7, over 99% of the cyanide will exist as HCN. At a pH of 9.3 – 9.5, CN – and HCN are in equilibrium, with equal amounts of each present.
