2. 50 ml of potassium chloride solution was potentiometrically titrated with a standard silver nitrate solution with a molar concentration of 0.1 mol/l. We obtained the following results (Vt, ml – volume of added titrant):
Vt 23.5 24.0 24.2 24.3 24.4 24.5 25.0 25.5
EMF, mV 146 165 194 233 316 340 373 385
Plot integral and differential potentiometric titration curves and determine the molar concentration (mol/l) and mass (g) of chloride ions in the analyzed solution.
