44. Solution to Chemistry Problem

1. Below are the data obtained in determining the surface tension of propionic acid solutions in water depending on the concentration of the acid at 293 K:
C, g/l 0.00 0.100 0.238 0.952 2.000 3.806
σ , mJ/m2 72.8 65.0 60.0 46.0 38.0 34.0
Plot the dependence of propionic acid adsorption on composition.
