WebVarious experiments to observe the effects of detergents and soaps on the surface tension of purified and hard water. A fine insoluble powder, such as talcum powder, is sprinkled on a clean water surface in a beaker, a drop of detergent or soap solution added to the centre, and the effect observed as the surface tension of the water is changed. WebApr 17, 2024 · Surface tension is a force which causes a layer of liquid to behave like an elastic sheet or skin. Molecules of water are more attracted to each other than other molecules, as water is a polar molecule. The positive hydrogen end of one molecule is attracted to the negative oxygen end of another water molecule.
