Abstract
The thermodynamic molar absorptivity of complex formed by 1:1 coordination color reaction of tiron with highly charged cation In3+ has been measured spectrophotometrically at 20.0+/-0.1 degrees C, using NaClO4 as supporting electrolyte. The influence of å on linear relation between molar absorptivity and ionic strength has been investigated. At å = 6.5, the thermodynamic molar absorptivity lg epsilon(o) was found to be 3.69.
