## Abstract The reaction between Sb(III) and [Co^III^W~12~O~40~]^5β^ proceeds with two, oneβelectron steps; formation of unstable Sb(IV) is the slow first step followed by its reaction with another oxidant in a fast step. The reaction rate is unaffected by the [H^+^] as there are no protonation equ
The kinetics of the interactions of the Keggin type heteropolyanion [CoWI2O4~l5-, with all the molecular and anionic forms of citric acid have been investigated spectrophotometrically in the pH range 0.60-5.45 a t 60Β°C. With the exception of the molecular form of the acid (H3L), all the other specie
