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
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.
