Molar Entropy/Enthalpy Values of H2SO3
Hey everyone!
Looking for the delta H and molar entropy values of sulphurous acid to do a calcultion. Looked as far as the CRC handbook. Can't seem to find them
anywhere. I do know that H2SO3 only exists in solution. Hmmmm....
Any input?
Thanks in advance!
P.S.- If it is in solution can I just use SO2 values?

You should use the values for aqueous SO2 if you have that. Also check this out:

If you don't have the heat of formation of aqueous SO2, you can use Hess's law and find the value you need with the heat of formation of SO2 and the
heat of solution of SO2.
