2. The analyzed solution of HCl and CH3COOH with a volume of 25 ml was placed in a volumetric flask with a volume of 100.0 ml. When titrating a 10 ml aliquot with 0.1 N NaOH solution, the following results were obtained:
V(NaOH, ml) 7.0 8.0 9.0 10.0 11.0 12.0 13.0 15.0 16.0
x, mS/cm-1 3.52 3.40 3.11 2.85 2.69 2.65 2.68 2.95 3.16
Construct a titration curve and calculate the molar concentrations and masses of substances in 100 ml of the analyzed solution.
