N2 - The formation and decay of In(II) in the acid pH range was investigated. Hydrated electrons react with In3+ with a rate constant of (2.8±0.4) x 1010M-1s-1 (ionic strength, 0.09 M). Isopropanol radicals and H atoms did not react with In3+. Other forms of In(III), such as InOH2+, its dimer and the In(III) tetramer were unimportant under our conditions. In2+ is an acid, pK= 4.5±0.2. It decays away by disproportionation (k= (1.3±0.3) x 109 M-1 s-1, oxidizes isopropanol radicals (k=(9.0±2.0) x 108M-1 s-1) and reduces H2O2 (k= 6.0±1.0) x 108 M-1 s-1). In+ is obtained as a relatively stable product by the reduction of In2+ with isopropanol radicals and by disproportionation of In2+.
