A Multipurpose Apparatus to Measure Viscosity and Surface Tension of Solutions: The Measurement of the Molecular Cross-Sectional Area of N-Proposal

Journal of Chemical Education, v81 n6 p850 Jun 2004

A multipurpose apparatus that can be used to measure the viscosity of solution by the Ostwald method and the surface tension of solution by the drop-weight method or by the capillary-rise method is developed. The apparatus is convenient for in-situ preparation of solutions of different concentrations and avoids the error that frothing of the liquid surface introduces into measurements.
