Potentiometric Titration in Non-Aqueous Solutions

Potentiometric Electrode Systems In Nonaqueous Titrimetry

“…The ratios of the dissociation constants of mono-, di-, and triphenylacetic acids in methanol, ethanol, and water have been measured using a concentration cell with quinhydrone--gold electrodes (114). The determination of the acidity of oils has been studied by titration in butanol (29,50,177) and in isoamyl alcohol (176). Ruehle (169) has shown that acetone, anisóle, and dioxane can be used to enhance the solvent powers of butanol without interfering with the functioning of the quinhydrone electrode in this solvent.…”

Determination of Acidity in Insulating Oil

“…The use of quinhydrone with oils that contain peroxides should be questioned. When using the glass electrode no quinhydrone and conducting salt are necessary in the titration medium (2,4,10,11,12). However, peroxides present an unavoidable difficulty, in that they are attacked A. Titration of 0.9 cc.…”

Potentiometric Titrations. A Review with Bibliography

“…The maximum pulse per drop of reagent marks the end point. Another manner in which a vacuum tube voltmeter may be used to get differential readings is to reset the meter after each drop is added and a steady reading is found, as proposed by Clarke, Wooten, and Compton (92).…”
