Imagine that you are titrating 30.00 mL of 0.100 M KOH with 0.100 M HBr (HBr is in the buret). Calculate the pH of the solution after 30.00 mL of acid is added to the base.

Not sure how to do this problem, my standard method is definately not working since you can't take log(0). Any ideas on what I can do?
