2007-8-24  At approximately pH 9.3, half of the total cyanide exists as hydrogen cyanide and half as free cyanide ions. At pH 10.2, more than 90% of the total cyanide was present as free cyanide CN − while at pH 8.4, more than 90% existed as hydrogen cyanide. This is important because hydrogen cyanide has a relatively high vapor pressure (100 kPa at 26°C) and consequently volatilizes at the liquid ...
