Solution chemistry in dichloroacetic acid. II. Conductance studies of acids and bases in dichloroacetic acid

Abstract

Conductance measurements of protonic acids and Lewis acids have been carried out in dichloroacetic acid at 25 ± 0.l°C. Λ₀, values have been determined for these acids; it is found that there is extensive ion-pair formation in solution. The role of CHCl₂CO₂H as a differentiating solvent has been explored. Triple-ion formation for SbCl₅ and AlBr₃ is indicated which is supported by log C against logΛ_c curves. Similar trends have been indicated for organic tertiary bases in dichloroaceticacid. Conductometric studies of the same salts in dichloroacetic acid have also been carried out. Fluorosulphuric acid has been developed as an acidic titrant for the estimation of bases in dichloroacetic acid.
