Two possible colorimetric indicators for use in studying magnesium complexation kinetics.
Complexation-rate equilibrium data for 25.0 degrees and 0.5M KCl medium are presented for two colorimetric indicators for magnesium: 3.5-dinitrosalicylic acid and kojic acid. The forward rate constants are both consistent with an S(N)1 mechanism and the complex formation constants are 145 and 390 1./mole respectively.
