Determine the direction of the following reaction from the relative strengths of acids and bases:
H2S(aq) + C2H3O2-(aq) yields Hc2H3O2(aq) + HS-(aq)
The book says this will favor the reactants. I'm confused...shouldn't this be neutral because both reactants and products have weak acids and bases?
But H2S is a weaker acid than HC2H3O2.
Thanks. Is there a way to tell how one acid is weaker than the other or do you have to memorize the charts?
