WebNov 27, 2015 · Surface tension can change with the change with medium that is just above the liquid. For instance, If the medium is air the surface tension of water is 72 × 10 − 3 N / m, but if the medium is vapour that will be 70 × 10 − 3 N / m. If there is any oil or oily compounds on the free surface of the water, then surface tension will be reduced. WebThen increase in surface tension should be due to undissociated bile acids much more surface active than the dissociated ions. You see the same effect with soap solutions at neutral pH. green market cafe catering
