(Re-posting because no one was answering chemistry questions)

if you have 100mL of 0.1M acetic acid (ka = 1.8x10(-5)what is the pH after 10mL NaOH is added? I came up with an answer of 2.895, but i'm not sure if its right.

I saw your post last night and started to answer it before I went to bed; however, you don't have enough information to answer. You don't have the concn of the NaOH listed. So 10.00 mL of WHAT concn NaOH.
