4. The HCl solution to be analyzed was diluted in a volumetric flask to 200.0 ml and a 50.00 ml aliquot was titrated potentiometrically with 0.1000 M NaOH. Plot titration curves in pH - V coordinates and determine the mass (mg) of HCl in solution using the following data:
V, ml (NaOH) 1.50 1.80 1.90 1.95 1.98 2.00 2.02 2.05 2.10
pH 2.64 3.05 3.36 3.64 4.05 6.98 9.95 10.53 10.65
