Want vapor pressure vs pH graph for HCN

⇦ (tip: readers rarely show interest in abstract questions, but people's actual situations usually prompt responses)

Hi,
I am trying to find a graph of the vapor pressure vs pH value for a solution of HCN and water, and a graph of concentration of HCN in water with respect to pH value.
Can you help me?.
Thank you,

Don't take this personally, cousin Abbadi, but the most interesting thing about your inquiry is why you might want that graph :-)

I make that suggestion as the website operator because long experience has proven that people rarely invest the time & effort to track down such a graph for a stranger who doesn't offer an introduction -- whereas they often go far out of their way to participate in a small way to the solution to an interesting problem. So please introduce us to who you are and why you want it :-)

The vapor pressure is dependent on the amount of free HCN in the water solution, which is dependent on pH.
