What is Equilibrium studies of the cobalt(III) and chromium(III) aquapentaammine/hydrogen chromate complexation reaction about?
The complex equilibria between [M(NH3),(OH2)13+ (M = Co, Cr) and HCrOhave been determined spectrophotometrically in acidic aqueous solution 01 = 0.50 M). The stability constant, Kc = [M(NH3)5(HCr0,)2']/[M(NH,),(OH2)3+][HCrOJ, is 1.55 f 0.02 M-l for M = Co and 3.56kO.62 M-' for M = Cr at 25°C. The chromate complex exists in both [M(NH3),(HCr04)]2+ and [M(NH,),(CrO,)]+ forms. The acidity constants for the protonated chromate species at 25°C are (4.43 kO.05) x lop3 M (Co) and (3.37kO.63) x 10m2 M (Cr). The temperature dependence of the chromium(II1) complexation with HCrO,-is described and the resultant thermodynamic parameters are discussed in relation to other chromate reactions.
