Dissociation Constant of Anisic (p-Methoxybenzoic) Acid in the System Ethanol-Water at 25 °C

The dissociation constant of anisic (p-methoxybenzoic) acid in the system ethanol-water was measured at 25° C by a combination of spectrophotometric and electrometric methods. Percentage by weight of ethanol in the solvent system varied from zero to 83.43. The value of K varied correspondingly from...

Sumario:The dissociation constant of anisic (p-methoxybenzoic) acid in the system ethanol-water was measured at 25° C by a combination of spectrophotometric and electrometric methods. Percentage by weight of ethanol in the solvent system varied from zero to 83.43. The value of K varied correspondingly from 3.22×10(−5) (pK=4.492) to 3.34×10(−8) (pK = 7.476).
