2. The mixture of HCl and CH3COOH to be analyzed was placed in a 50 ml volumetric flask and filled to the mark with water. When titrating 10 ml of a solution of 0.1 M NaOH (K = 1.104), the following results were obtained for three variants of the mixture:
Vst, ml 7.0 8.0 9.0 10.0 11.0 12.0 13.0 14.0 15.0 16.0
χ cm 2.62 2.35 2.08 1.96 2.00 2.03 2.06 2.38 2.74 3.10
Construct a titration curve and determine the mass of hydrochloric and acetic acids in the original solution (g).
