Sažetak
The rate of aquation of [Co(NH3)s (DMSO)] Bra was measured
in solutions containing the surfactant cetyltrimethylammonium
bromide (CTAB) over the concentration range 9.55 x 10-4 mol dm-3
to 0.450 mol dm-3• This large change in CTAB concentration affected
the rate very little and no significant amounts of Co(NH3)sBr2+
were formed .. It was concluded that, if Br- counterions were concentrated
in the microregions around the positively charged CTAB
micelles, then there was no corresponding increase in the formation
of Co(NH3)s (DMS0)3+. Br- ion-pairs in this region with subsequent
Co(NH3)sBr2+ formation.
