Benzoic acid partition coefficient. As the primary example of a more exact expression of the Partition Law it was shown that benzoic acid distributed itself between benzene and water so that Where Cs is the concentration of benzoic acid in benzene Cw is the concentration of benzoic acid in water and K is a constant combining the partition coefficient for the benzoic acid monomer and the dimerization constant.

Estimated soil adsorption coefficients of 65 and 3101SRC obtained from o-chlorobenzoic acids water solubility 2087 mgL at 25 C2 and octanolwater partition coefficient 2053 respectively can be obtained using an appropriate regression equation. These values indicate that it will display moderate to high mobility in soil4. Estimated bioconcentration factors of 20 and 641SRC obtained from m-chlorobenzoic acids water solubility 450 mgL at 25 C2 and octanolwater partition coefficient 2683 respectively can be obtained using an appropriate regression equation.

These values indicate that it will not bioconcentrate in fish and aquatic organismsSRC. The acid dissociation constant for an acid is a direct consequence of the underlying thermodynamics of the dissociation reaction. The pK a value is directly proportional to the standard Gibbs free energy change for the reaction.

The value of the pK a changes with temperature and can be understood qualitatively based on Le Châteliers principle. When the reaction is. Benzoic acid associates in the oil phase and dissociates in the aqueous phase The species common to both the oil and water phases are the unassociated and undissociated benzoic acid molecules.

Solubility Partition Coefficient Dissociation constant Hydrogen Bonding Ionization of Drug Redox Potential Complexation Surface activity Protein binding Isosterism 1. The solubility of a substance at a given temperature is defined as the concentration of the dissolved solute which is in equillibrium with the solid solute.

Solubility depends on the nature of solute and. Molar concentration also called molarity amount concentration or substance concentration is a measure of the concentration of a chemical species in particular of a solute in a solution in terms of amount of substance per unit volume of solution. In chemistry the most commonly used unit for molarity is the number of moles per liter having the unit symbol molL or moldm 3 in SI unit.

0100 mol dm-3 benzoic acid. A sharp fall between pH 11 and pH 75 Midpoint of steep slope at about pH 9. Partition coefficient K pc is the equilibrium constant which relates the concentration of a solute partitioned between two immiscible solvents at a particular temperature.

LogD refers the the wateroctanol partition coefficient at a specific pH normally pH 74.

For ionizable compounds acids and bases logD would be altered by pH because the distribution of. The constant is defined as the partition coefficient K. K C S C G.

Where C S is the concentration of the analyte in the sample after equilibrium the term C L may be used if the sample is a liquid and C G is the concentration of the analyte in the gas phase after equilibrium. The partition coefficient is lowered as the temperature increases and also varies with changes in the matrix. Benzoic acid Skin Irrit.
