Acid-base titration help please? Thank you very much!If a titration of a 10.0 mL sample of unknown concentration acetic acid with 0.100 mol/L...

If you do a graph of pH vs. mL of NaOH, you will see that
the pH gradually rises with each addition of the NaOH until all of the acetic acid in
the sample is neutralized.  Then a small addition of NaOH should result in a much
greater increase in the pH of the solution.

Once you have
your graph and have identified the amount of NaOH needed to neutralize the acetic acid,
you can then calculate the concentration of the acetic acid
solution.

The relationship you will use is the
following:

the mL of NaOH * concentration of the NaOH = mL
of acetic acid * concentration of the acetic acid.

You get
the mL of NaOH from the graph; you know the concentration of the NaOH; you know the mLof
acetic acid so you can solve for the concentration of the acetic acid
solution.
