Contrary to surfactant solutions, aqueous electrolytes possess surface tensions higher thanpure water.
is there? If not, why?
Rather unexpectedly, such electric fields (~1 MV m-1) apparently increase water's surface tension by about 2%...There is some dispute over the effects of electric and magnetic fields on surface tension. Electric and magnetic fields have been reported to lower the surface tensions of natural water by up to 8% . However, it has been noted elsewhere that surface tension measurements are too sensitive to impurities to provide reliable data . Recently, high magnetic fields (10 T) have been reported as increasing the surface tension of water by almost 2%, with this being possibly due to the stabilization of the hydrogen bonds or the dampening of surface waves
