1. In the potentiometric titration of an aqueous potassium chloride solution with 0.09603 M silver nitrate, the following data were obtained: Volume of AgNO, (mL) E versus SCE (V) 10.00 20.00 25.00 27.00 28.00 28.80 29.00 29.10 29.20 29.30 29.40 29.50 29.60 29.70 30.00 30.50 31.00 33.00 +0.062 0.085 0.107 0.123 0.138 0.161 0.173 0.180 0.192 0.221 0.228 0.304 0.314 0.321 0.336 0.348 0.359 0.389 A silver wire indicator electrode and a saturated calomel reference electrode (SCE) were employed. Plot E versus V (i.e., the measured potential in volts as a function of the volume of added titrant in ml), as well as the first derivative AE/AV versus V (using the average volume for V). Using the first derivative method, locate the equivalence point, and calculate the millimoles of chloride ion in the sample. 1.
