Step 1
If the pH is lower than the pKa, the environment is more acidic and the substance will primarily be in its acid form (HA). If the pH is higher than the pKa, the environment is more basic and the substance will primarily be in its base form (A-). In this case, the Show more…

(pka of benzoic acid= 4.20) calculate the pH of a solution made from combining 0.300 M benzoic acid with 650 ml and 0.500 M KOH with 20 ml.
Dominique Jan T.
The pKa of benzoic acid is 4.2; the pKa of p-aminobenzoic acid is 4.65; the pKa of p-nitrobenzoic acid is 3.61. Rank these compounds in increasing order of acidity and account for these values.
Sri K.
What should the molar concentrations of benzoic acid and sodium benzoate be in a solution that is buffered at a pH of 4.55 and has a freezing point of -2.0 C? (Assume complete dissociation of sodium benzoate and a density of 1.01 g>mL for the solution.)
