Product description
2. Calculate the surface tension of butyric acid solutions at 22°C and concentrations: 0 - 0.02 - 0.04 - 0.08 - 0.16 kmol / m3, if the surface tension of the solvent is 0.072 n / m, the area covered by one mole of the substance is 1.02*105 m2, surfactant substance density 880 kg/m3. Build a graph: tension - concentration. Determine the maximum adsorption, the cross section of the molecule, its length, as well as surface activity and Gibbs adsorption at C = 0.02 kmol/m3, b = 70 m3/kmol.
