WebCyanide in Water is expressed in terms of cyanite ion which is present in water in the form of hydrogen cyanide (HCN). The effect of pH on cyanide is of great importance. The lower the pH, the greater the cyanide toxicity. HCN is largely undissociated at pH values of 8 and less. The toxicities vary markedly with pH.
