Abstract:Using an opitical method according to Briegleb [3], we were able to prove the existence of a 1:l-complex KO2in aqueous solution. The stability constant of this weak complex can be estimated to be K'," = 1.0 I/mole. From solubility data [4] we calculated K2C5 " = 0.8 I/mole.The results show [51 that the yellow adducts are charge transfer complexes of the Mulliken type [6], in which the iodide ions act as donors and the SOzmolecules as acceptors. Infrared spectroscopic measurements in acetonitrile led to the sam… Show more
