Calculate the pH of a 0100 M KCN solution. Calculate the pH of a 0100 M KCN solution, (KOH) and a weak acid (HCN), and thus the salt in aqueous solution will have a basic pH One needs to then look at the hydrolysis of the cyanide anion, CN^-, which is as follows:, CN^- acts as a base, and so one need to know the Kb for CN^-) Looking up the Ka for HCN, I find it to be 67x10^-10.

According to an RMPP Technical bulletin dated 10/13/94, a NaCN solution will contain roughly 16% HCN at a pH of 10. At pH 12 or above, the concentration of HCN in the NaCn solution will be less than 1%. I believe these data came from a 1993 DuPont paper which was based on Data based on work by D. Milne, 1950, for dilute cyanide solutions at

In this case the problem becomes more economic because this high cyanide concentration requires a high detox reagents (hydrogen peroxide, H2SO4, SMBS, Copper sulfate) concentration. High Do level can be the solution Yes, but still it depends and only test works and cyanide control suggest tank can lead for an optimum dosage.
