A solution is prepared at that is initially in benzoic acid , a weak acid with , and in sodium benzoate . Calculate the pH of the solution. Round your answer to decimal places.
Answers: 3
![pH=pKa+log(\frac{[base]}{[acid]} )](/tpl/images/0729/0662/33848.png)
![pH=-log(Ka)+log(\frac{[base]}{[acid]} )\\\\pH=-log(6.3x10^{-5})+log(\frac{0.33M}{0.42M} )\\\\pH=4.1](/tpl/images/0729/0662/ae838.png)
