Product description
During potentiometric titration of an aliquot of the analyzed solution of hydrochloric acid with a volume of 20.00 ml of 0.01000 mol / l sodium hydroxide solution, the following results were obtained (V is the volume of the added guarantor):
V, ml 15.00 16.80 17.20 17.40 17.60 17.80 18.20 20.00
pH 3.15 3.72 4.09 4.57 9.42 9.90 10.26 10.80
Calculate the molar concentration of hydrochloric acid in the test solution using the following method to determine the equivalence point (TE).
Which electrodes (platinum, kolomel, silver chloride, glass) can be used as an indicator electrode, and which ones can be used as a reference electrode for this titration?
Method for determining TE
b) Graphic - along the titration curve in the coordinates ΔpH / ΔV - V
c) Graphical (Gran method) - along the titration curve in the coordinates ΔV / ΔpH - V
