Inflection points on some S-shaped curves
(Scientific Research Publishing, 2014)
This paper refers to inflection point—the fundamental property of S-shaped curves. In this paper, the inflection points are related to pH titration curve pH = pH(V), and to the curve σ = σ(pH) in-volved with surface tension, σ.
