How to find pH during titration with excess acid?
« on: March 23, 2014, 03:24:21 PM »
I am having trouble finding the answer to this question:
Consider the titration of 48.5mL of 1.1M NaOH with 1.0 M HCl. Find the pH.
after the addition of a large excess of acid (in comparison with the acid volume needed to reach the equivalence point).
This is all the information that is given. I am not sure what 'large excess' actually means.

pH of the mixture will go asymptotically to...

Yep.

You can easily express [H+] in terms of volume of added HCl.
