Notizen: A detailed kinetic study of the reaction between toluidine blue (tolonium chloride) (TB+Cl-) and stannous chloride is carried out in aqueous hydrochloric acid. The depletion kinetics of toluidine blue were spectrometrically monitored at 626 nm. The reaction had fractional order with respect to toluidine blue (one half), three halves with respect to Sn2+, and first-order dependence on H+ ion. Stoichiometric ratio between reductant and oxidant is 1:1. During the reaction Sn2+ is oxidized to Sn4+ and toluidine blue is reduced to colorless base in two univalent steps. © 1993 John Wiley & Sons, Inc.
