Product description
- Potentiometric titration was carried out V = 50.00 ml = 0.050 l of the analyzed solution of potassium chloride KCI with a standard solution of silver nitrate AgNO3 with a molar concentration c(T) = 0.1000 mol/l. The following results were obtained (V(T) is the volume of added titrant, E is the EMF of the galvanic circuit):
V(T), ml 23.50 24.00 24.20 24.30 24.40 24.50 25.00
E, mV 146 165 194 233 316 340 373
Plot potentiometric titration curves and determine the molar concentration c(Cl) of chloride ions in the analyzed solution using a graphical method.
