WebAt pH above 4.76 acetate ion is formed, which cannot be permeate through the liquid membrane. The pH value of the feed phases of 0.1 M, 0.05 M and 0.01 M concentrations of acetic acid was found to be 3.23, 3.65 and 4.05 respectively. These pH values are lower than the pKa value of acetic acid, enabling permeation of acetic acid across the membrane. WebGlycolic acid is slightly stronger than acetic acid due to the electron-withdrawing power of the terminal hydroxyl group. The carboxylate group can coordinate to metal ions forming coordination complexes. ... Glycolic acid is a useful intermediate for organic synthesis, in a range of reactions including: oxidation-reduction, esterification and ...
