Kinetic and Spectroscopic Evidence for the Formation ofIon-pairs between Crystal Violet and PerchlorateIon†

Abstract

Kinetic data for the inhibition of the reactionbetween Crystal Violet (CV) and hydroxide ions by perchlorateions are used to determine the equilibrium constant for theformation of ClO₄ –CV ion-pairs; K isobtained as 110±14 dm³ mol¹ at 25°C and ionic strength (I )=0 mol dm³ .
