Abstract:

The maximum bubble pressure method is a classical method to determine the surface tension of solution in physical chemistry laboratory. Due to the influence of various factors, the results from students have large standard deviation. In this study, concentration and temperature were used as variables to explore experimental conditions, and the results obtained were in good agreement with literature values.

Key words: Maximum bubble pressure method, Surface tension, Conditional optimization
