H2S+NaOH ==> NaHS + H20

H2S+NaOH ==> NaHS + H20

H2S+NaOH ==> NaHS + H20

(OP)
closed thread798-141763 discussed making NaHS from H2S.  I need to know the heat of solution.  When the H2S is absorbed into the NaOH, how much heat is released?  You would think this would be readily available, but I can't find it.

RE: H2S+NaOH ==> NaHS + H20

Re 'H2S is absorbed into the NaOH.'
Would this be crystalline or molten NaOH?
Maybe no such data. But, for aqueous solutions containing Na+ & OH-, lots of data. Not as straightforward as you might hope, since multiple equilibria. At high pH, the H2S solubilizes as HS-(aq.). A good explanation is A Discussion of the Effect of pH on the Solubility of Hydrogen Sulfide by John J. Carroll.

Thanks Kevin for the submittal.  What I'm really looking for is the heat generated from this reaction.  Like for every lb of H2S absorbed into 50% NaOH ==> x,xxx BTU of heat is generated.
