“…Although the changes in the potential obtained with TBAH or KOH Figure 4. (a) The effect of the indicator electrode on the shape of the end-point inflexion in the potentiometric titration of benzoic acid in isopropanol using the following titrants: (1) sodium methylate, (2) TBAH, and (3) KOH; (b) the effect of the indicator electrode on the shape of the end-point inflexion in the potentiometric titration of (1-7) stearic acid and (8-10) α-Nitroso-β-naphthol in iso-propanol using the following electrodes: (1), (3), and (8) pyrite; (5), (6), and (9) chalcopyrite; and (2), (4), (7), and (10) glass; and the following titrants: (1), (2), and (5) KOH; and (3), (4), and (6 -10) TBAH; (c) the effect of the indicator electrode on the shape of the end-point inflexion in the potentiometric titration of (1-7) benzoic acid and (8-11) stearic acid in tert-butanol using the following electrodes: (1), (3), (8), and (10) pyrite; (5) and (6) chalcopyrite; and (2), (4), (7), (9), and (11) glass, and the following titrants: (1), (2), (5), (8), and (9) KOH; and (3), (4), (6), (7), (10), and (11) TBAH. a c b and the chalcopyrite sensors are lower than for the pyrite sensor, they are distinctive enough to allow the precise determination of the TEP in the titration of very weak acids.…”
