What is the pH of a solution with 0.122 M of CH3COONa, 0.500 M of CH3COOH acid, and hydrogen sulfide bubbled up to saturation (0.1 M)?
Acetic acid: Ka=1.75E-5
Hydrogen sulfide: Ka1=9.6E-8 Ka2=1.3E-14
I think this is supposed to be a simple calculation because the question leaves only a small amount of blank to do this question in. Can I assume that since there is a buffer in the solution (acetic acid/acetic salt), the acidic dissociation of H2S has no effect?
Thanks a lot
