124. Determine the concentration of the NaOH solution (g/dm3) used for washing cellulose bleached with hypochlorite, if 10 cm3 of an alkali solution was placed in a volumetric flask with a capacity of 100 cm3, 10 ml of the resulting solution was transferred to the capacitive cell of a high-frequency titrator and titrated to 0.1 mol/dm3 saline solution. As a result of the analysis, the following relationship was established between the readings of the recording device and the volume of added titrant
C mg/dm3 0 2.0 3.0 4.0 5.0 5.5 6.0
