The dissociation constant of acetic acid in 50 mass % ethylene carbonate-water solvents has been determined at eight temperatures from 20 to 55C by emf measurements of cells without liquid-junction containing hydrogen electrodes and silver-silver chloride electrodes. Acetic acid is weaker in the ...
still further, which leads them to the view that Maclnnes and Shedlovsky's values are in error. The reason for this discrepancy is that in Jeff ery and Vogel's experiments the hydrogen with which the acetate ion unites comes not from the water but from the carbonic acid present in it....
Dissociation constant of Acetic Acid « on: November 26, 2017, 03:59:50 AM » Hello everyone,I had Acid-Base lab that need to determine Ka and concentraion but I'm confused on how to calculate concentration of CH3COO.Equation is : H2O + HC2H3O2 H3O + C2H3O2Concentration of Acetic...
The Dissociation Constant of Acetic Acid in Water-Ethylene Carbonate MixturesHydrochloric acid solutions (0.05–1.18m) containing p-nitroaniline (8×105M) as indicator base have Ho values which increase with increase of ethylene carbonate (EC) content in the solvent mixture for a fixed molality of ...

The release of the proton, described by the equilibrium reaction above, is the root cause of the acidic quality of acetic acid. The acid dissociation constant (pKa) of ethanoic acid in a solution of water is 4.76. The conjugate base of acetic acid is acetate, given by CH3COO–. ...
AAB often face adverse effects from organic acids such as acetic acid. Because of the unique physicochemical properties of organic acids, with a low dissociation constant (Ka), acetic acid largely exists in its undissociated form, allowing it to pass through the cell membrane and into the cell...

Acetic acid is a weak organic acid exerting a toxic effect to most microorganisms at concentrations as low as 0.5 wt%. This toxic effect results mostly from acetic acid dissociation inside microbial cells, causing a decrease of intracellular pH and metabolic disturbance by the anion, among other ...
