138. For high-frequency titration of a caustic soda solution (NaOH), used in the refinement of cellulose to increase its content of α-cellulose, 20 cm3 of the test solution were diluted in a measuring flask with a capacity of 250 cm3 and 5 cm3 of the resulting solution were titrated in a capacitive cell of a high-frequency titrator with a solution with a titer for CaO equal to 0.002842 g/cm3. Determine the concentration of caustic soda (g/dm3) using the following high-frequency titration data:
VH2SO4, cm3 0 1.0 2.0 3.0 3.5 4.0 5.0 6.0 7.0 8.0 9.0
I, μA 14 32 55 76 82 70 60 48 35 24 12
