Abstract: The dissociation constants and ionic products of water and ethanol, equilibrium constants of the OH^- + ROH reversible H₂O + RO^- reaction, and alkoxide and hydroxide ion activity ratios were determined in the water-ethanol system using various Gibbs energies of hydrogen ions transfer ΔG_tr°(H⁺). Validity of the Rochester equation is discussed on the basis of various literature data.
