title: A study on the theory of action of reversible redox indicators.
abstract: A new approach is made to the evaluation of transition potentials and transition ranges for redox indicators, based on the idea that to see the first colour change in a two-colour indicator system, the eye needs a certain minimum amount of the developing colour in addition to the threshold amount. The approach is applied to ferroin and shown to explain the colour changes observed for this indicator.
