Vapor pressure for sulfurous acid (SO2 aq soln)
Vapor pressure for sulfurous acid (SO2 aq soln)
(OP)
I'm looking for data on the vapor pressure of sulfurous acid (SO2 in an aqueous soln). The references that I've found are very incomplete in this area.
Thanks,
Thanks,

If you do not have access to a technical library, you can contact suppliers such as Dupont for the informatino.

20°C 1.565e-5
30 1.19e-5
40 9.08e-6
50 7.08e-7
60 5.49e-6
keep in mind that SO2 or H2SO3 is a weak acid, and that if the pH is above 2, some of the SO2 will be hidden as HSO3- or SO3--ions
