Product description

  • At 25 C, the surface tension of aqueous solutions of propionic acid depends on its molality as follows

s, mol/kg H2O 0.263 0.837 1.466 3.741

b, mN/m 60.0 49.0 44.0 36.0

Plot b versus lnc and determine from it the excess surface concentration G. Find the area per molecule of acid.
