Abstract

The oxidation reaction of cobalt(II) with sodium peroxide in aqueous solution in the presence of picolinic acid was investigated by visible spectroscopy. It was possibie to put into evidence two $\mu$ -peroxo bridged species, with complexation ration L/M = 2:2 and 4:2 respectively (T = - 5°C, ionic strenght 1,2M by $NaCl0_4$ and pH 2,40). The conditional concentrations quotients at equilibrium and molar absorptivities were determined using some graphical methods.
