Calculate the pH of a solution that is 0.291 M acetic acid and 0.123 M sodium acetate. The Ka of acetic acid is 1.76×10^–5 at 25°C. What is the pH of this mixture at 0°C?
Answers: 1
![pH = pKa + \log \frac{[sodium \ acetate]}{[acetic \ acid]}](/tpl/images/0932/3481/1f523.png)
![= 4.75 + \log \frac{[0.123]}{[0.291]}\\\\= 4.75+ \lg(0.422680412)\\\\=4.75-0.373987878\\\\=4.37601212\\\\=4.37](/tpl/images/0932/3481/5061d.png)
