    1. The problem statement, all variables and given/known data

    2. Relevant equations


    3. 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"?

    Whoops, I meant C. Sorry and thanks!
