Thanks a lot! I realized that I forgot to account for the volume change when I calculated my molarities for the base and the acid, and that was enough to get the pH off by 0.01.
*March 18, 2011*

**Chemistry**

Okay, so I found the ion concentrations through the Henderson-Hasselbalch equation, and the concentrations I got: [Acetic Acid] = 0.036525666 [Acetate] = 0.063474334 I got the same concentrations as when I did my ice chart, and I also got the same delta pH, which was -0.266.
*March 18, 2011*

**Chemistry**

Here's what I did: So I set values for: [Acetic Acid] = y [H3O+] = 10^-5 [Acetate] = 0.1M - y Ka = 10^-4.76 And from the equation: Ka = [Acetate][H3O+]/[Acetic Acid], I found y, or the molarity of acetic acid, to be 10^-6/(10^-5 + 10^-7.46). And from this, I also got the ...
