### 13.11 -- Buffer Solution Problem

Can someone show me how they set up problem 13.11 -- the book skips a step and I'm not sure how they got their initial pH.

Thanks!

The initial pH for this problem was determined using the Henderson-Hasselbalch equation:

$pH = pK_a + log(\frac{[A^-]}{[HA]})$

Where A- is the conjugate base and HA is the acid.
