146. To determine the total alkalinity of treated wastewater from sulphate pulp production, a water sample of 200 cm3 was potentiometrically titrated with a 0.1 mol/dm3 solution of H2SO4. Based on the table data, construct a differential titration curve and calculate the alkalinity of the analyzed water in mmole/dm3.
V H2SO4. cm3 1.0 1.8 3.0 6.0 8.0 8.5 10 11 12 13 14
ΔpH/ΔV 0.62 0.30 0.28 0.25 0.30 0.40 0.68 0.49 0.36 0.22 0.10
