Product Description
8. The analyzed hydrochloric acid solution was diluted with water in a volumetric flask to 100.0 ml and a 15 ml aliquot was titrated potentiometrically with a 0.1 M sodium hydroxide solution. Plot titration curves in coordinates ∆рН/∆V – V and determine the mass (mg) of hydrochloric acid in solution using the following data:
V(NaOH), ml 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
V(NaOH), ml 1.50 1.80 1.90 1.95 1.98 2.00 2.02 2.05 2.10
