What is formed in the reaction between hydrogen sulfide and aqueous sodium carbonate? My guesses are sodium sulfite and/or sodium hydrogen sulfite. However, the equations don't seem to balance properly whenever I try to do it. For example:
$$\ce{H2S(g) + Na2CO3(aq) -> Na2SO3(aq) + H2(g)}$$
It seems quite strange that hydrogen gas would be produced in this kind of reaction. Whatever I do, I end up with a bunch of hydrogen atoms that can't combine with any oxygen, and I'm sure I'm missing something.
