Surface Tension of a Surfactant Molecule's Aqueous Solution
Not what you're looking for?
The surface tension of an aqueous solution of a surfactant molecule is measured as a function of concentration. The data is shown attached in a plot of surface tension vs. weight percent surfactant. In a few sentences, explain what is happening and why. How will the appearance of the solution differ at 0.001 weight percent versus 1 weight?

Solution Summary
The expert examines surface tensions of a surfactant molecule's aqueous solution.
Solution Preview
Surface tension decreases as surfactant is added. Surfactants usually contain hydrophobic chains with hydrophilic heads. These hydrophilic parts can now replace some water molecules on the surface. As a ...
