A method is described to measure rapidly the superficial tension of any liquid, and to measure it with precision as a function of a continuous variation f the solute concentration. The method has been tested with 3 different surfactants. The first is an anionic one, sodium dodecyl sulfate (SDS...
WHEN surface tension is determined by the dropweight method, the drops must be allowed to fall as nearly as possible under the influence of gravity alone. In practice, the time of formation of a drop should be not less than five minutes....
