193. During the conductometric titration of a sodium acetate solution, a solution of hydrochloric acid with a concentration of 0.2 mol / l was added in portions to 50 ml of the solution and the electrical conductivity was measured. The following data were received. Construct a conductometric titration curve, set the equivalent volume of titrant (Vte) and calculate the concentration of sodium acetate in the solution. Explain the behavior of the conductometric titration curve.
