The rate of oxidation of Ge(II) chloride by large excess of ClO2− ions in HCl, NaCl and Na2SO4 mixed solutions was polarographically observed at various H2O+ and Cl− ion concentrations. The observed rate constant, kobs, is expressed by ko=Kobs/(ClO3−)={k1,(H+)+k2K1(Cl−)2+ K3K2(SO42−)} (H+)/{(H+)1+K1(Cl-)2 +K2(SO42−)} for the following reaction processes, The values were obtained aa k1=1.5410-3liter2 mole2− sec-1, k2=5.00×10-2liter2 mole2− sec-2 and k2=4.30×10-3liter2 mole2− sec-2, K1=1.80× 10-2, K2= 2.43×10-2 mole liter-1 at constant ionic strength I=0.50 M at 30°C. |
