57. Solution to Chemistry Problem

10. When titrating 50 cm3 of hydrochloric acid with a 0.1 mol/l NaOH solution, the following data were obtained:
VNaOH, cm3 0 2 4 6 8 10
w*103 (Ohm-1) – 1.42 0.85 0.70 1.15 1.62
Plot a titration graph in w-VNaOH coordinates. Determine the equivalence point. Calculate the concentration of hydrochloric acid.
