SURFACE TENSION

           ABSTRACT   Surface tension is defined as a cohesive molecular force acting on the surface of all liquids, which tends to force the solution to its smallest volume. The surface of the liquid, due to this force, becomes an elastic like film that exerts its force perpendicular to the surface of the solution. Surfactants are used to reduce surface tension, and their primary function is as an anti pitting agent, while the reduction of surface tension on the cathode surface also tends to enhance the effect of other additives on the character of the electrodeposit. The surface tension of a liquid influences the size of the drop that will be formed when the liquid is suspended from a glass tip. The capillary method, used to measure the surface tension of pure liquids very accurately, and stalagmometer is used to measure surface tension directly.
