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–. The pH of an ethanoic acid solution of 1.0M concentration is 2.4, which implies that it does not dissociate completely. ...

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....

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 ...
ChEBI: Acetic acid-d4 is a deuterated compound and a monocarboxylic acid. General Description Acetic acid-d4(deuterated acetic acid) is a deuterated NMR solvent containing 0.03% (v/v) TMS (tetramethylsilane). It is useful in NMR-based research and analyses. Its dissociation constant in deuteri...
CovaChem's LCMS Grade Acetic Acid is ideally suited as a chromatography additive for use in both HPLC and LCMS applications. Acetic acid is typically beneficial as a separations enhancer, and has a weak ion pairing effect in the mass spectrometer, making dissociation of from the analytes relativel...
