128. Solving a chemistry problem

Determine the change in the micellar mass of sulfanol in its aqueous solution with a change in the acidity of the medium, using the experimental data of the light scattering method.
Solution concentration Cm, kg/m3 1.0 2.0 4.0 6.0 8.0
The value of H * Cm / t) * 103 at
a) pH=1.8 0.96 1.04 1.12 1.25 1.32
b) pH= 6.8 0.074 0.083 0.92 1.04 1.18
c) pH=11.8 0.62 0.71 0.82 0.97 1.08
