Since these intermolecular forces vary depending on the nature of the liquid (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties.

WebSo, resist the urge to break the surface tension on your tent if it's raining out. And when you wash your hands, when we use detergents. If you washed your hands with just regular water and that's it, sometimes the surface tension's too great. These water molecules are too bound to each other. They form too big of a clump. It doesn't look like it. WebApr 23, 2016 · The surface tension sigma is a unique function of a[SDS], almost independent of [NaCl]. So my simple explanation is: when you add NaCl, you increase the activity of SDS since a[SDS] ~ sqrt(Na).
