Surface tension of a mixture
WebFIGURE 2. Next, explain the role of surfactants to students. A surfactant is a substance that reduces the surface tension of a liquid. For instance, a small puddle of water on a desk has high surface tension. But adding a surfactant such as dish soap to the puddle would reduce its surface tension and cause the water to spread out more. WebJan 18, 2012 · The density, viscosity, and surface tension of binary mixture of water+ethanol at 293, 298, 303, 308, 313, 318, and 323 K are reported and compared with the available literature data. The findings of these comparisons show how the measured data are reproducible from different laboratories.
