Homework Equations




The Attempt at a Solution


I chose C as if a strong "something" is added to a weak "something" then you won't get a strong curve. So acetic acid will be eliminated. If D or E was added, the equivalence point should have pH of 7 or less. Therefore I chose C. Is this correct? As the type of base and molarity of it is not indicated, I assumed it was NaOH and 1 M.

Cheers!

Initial pH of 1 - what does it tell you about the concentration of the H+? About concentration of the acid?

Actually the shape of the curve (especially after the equivalence point) is wrong.

This means the concentration of H+ is 0.1 M. Therefore D is the answer, right? So I guess the base and the graph curve aren't needed, only the initial pH.

Thanks!

D, which says "1M"?
