142. Solving a chemistry problem

Construct potentiometric titration curves in the coordinates E - V and ΔE / ΔV - V and determine the concentration of acetic acid if, when titrating 10.00 ml of the analyzed acid solution with a 0.1000 M KOH solution, the following results were obtained:

Vcon, ml 10.0 18.0 19.0 19.5 19.9 20.0 20.1 20.5 21.0
pH 4.76 5.71 6.04 6.35 7.06 8.79 10.52 11.22 11.51
