Titrimetric Study of Solubility of Solute Benzoic Acid and Their Partition in Water and Benzene Solvents
Chemical Science International Journal,
The solubility and distribution coefficient (K) of solute in solvent is depends on temperature and solute-solvent interaction, where the solute is partitioned between two immiscible solvents phase and dissociated into ionic form. Here, we have reported the titrimetric study for solubility and partition or distribution coefficient of benzoic acid (solute) in aqueous water and in organic benzene which are using as solvents. The benzoic acid solubility (in g/100g of solvent) in water and in benzene solutions have determined by titrimetrically. There is partitioning and concentration of such acid in these solvent phase by shake-flask and acid-base titration method as well. The benzoic acid solubility and their distribution between water and benzene as in different pH buffer solutions have been analyzed at room temperature (25°C) in acidic, neutral and basic (pH 4.0, 7.0 and 9.0) medium, respectively.
