7.18. Determine the surface tension of an aqueous solution of butanol if, after shaking it with benzene, the interfacial tension is 0.0355 J / m2. The surface tension of benzene at the interface with air is 0.0288 J / m2. How does introducing butanol into an aqueous solution affect the surface tension of water?
