Effect of pH on Benzoic Acid Solubilization and Its Partition in Water-Benzene Solvents

The solubility of a substance is determined by the solute-solvent interaction, pH, temperature, and ionic dissociation, among other factors, where the solute is partitioned between two immiscible liquid solvents. The solubility of benzoic acid (solute) as well as its partitioning between hydrophilic water and hydrophobic benzene, which are utilised as solvents at room temperature (25°C), are described in this paper. The distribution of the solute benzoic acid between these two solvents is investigated using the shake-flask and titrimetric methods, as well as the acid-base titration method. At several pH ranges (4.0, 7.0, and 9.0), the solubility of salt benzoic acid and their partition into water and benzene-buffer solutions were also investigated.
