Calculate the pH of a solution that is 0.115M benzoic acid and 0.140M sodium benzoate, a salt whose anion is the conjugate base of benzoic acid.


Express the pH to at least two decimal places.


Expert Answer

Step 1

Concentration of benzoic acid = 0.115 M

Concentration of Sodium benzoate = 0.140 M

Since the buffer solution is made up of benzoic acid and sodium benzoa...
