III. Experimental Section Reagent Used: Distilled water, n- butanol, any surface active material (optional) Equipment and Glassware: Du Nouy tensiometer, 50 ml glass-stoppered Erlenmeyer flask, 5-ml volumetric pipets, flask, stirrer Procedure: 1. Adjust the reading on the tensiometer to zero. Obtain the surface tension of distilled water by measuring the surface tension of the water, perform it for 3 (three) times. For precision we simply get the mean reading ( m) from these three ϒ measurement. Then get the Temperature of the distilled water. 2. Estimate the correction for the tensiometer ( ϒ corr ) by the difference between the literature values of the surface tension of water ( ϒ lit ) (request lab assistant for the data) from the mean reading ( ϒ mean ) that was recorded from 1 st step above. 3. After measuring the surface tension of the distilled water. Then proceed to the new

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
