What is the percent ionization of a 0.240 M solution of benzoic acid?
You need to prepare 100.0 mL of a pH=4.00 buffer solution using 0.100 M benzoic acid (pKa = 4.20) and 0.240 M sodium benzoate.
How much Benzoic Acid and Sodium Benzoate should be added in mL?
Determine the percent ionization of a 0.230 M solution of benzoic acid. The Ka of benzoic acid is 6.3 x 10-5.
