How do Sodium Sulfide and Sodium Hydrogen Sulfide differ in aqueous solution?



Since the Sulfide anion shouldn't exist in solution, I'd assume both form HS-, and eventually, H2S.

Is that correct, and if so, would there be any major differences in reaction speed, stability, etc?

Although the sulfide ion doesn't exist, a solution of sodium sulfide is much more basic compared to sodium hydrogen sulfide.

Sodium hydrogen sulfide forms no hydroxide when dissolving, not much at least, sodium sulfide forms around an equimolar amount of hydroxide.
