Notizen:
Acidity constants of 3, 4, 5 and 6-chloro-o-toluidinium ions are measured at 25°C in aqueous-ethanol solvents containing 0, 20, 35, 50, 65 and 80 wt% of ethanol by pH metry. The correction factor giving stoichiometric significance to pH meter readings have been evaluated for three different acid concentrations in each of the above mentioned solvent systems. Attempt has been made to correlate the strength of each of the anilinium ions with various solvent properties. HAMMETT-type relations have been derived for correlating acid strengths with structural properties.
