The products from the reaction of phenylazobenzenediazonium ion with aqueous alkali were studied by preparative methods with TLC and electronic and IR spectroscopy.The acidity constants of the diazonium ion and the diazohydroxide were determined spectrally and also from data on the kinetics of decomposition and azo coupling.The acidity of the phenylazobenzenediazonium ion, like that of the majority of organic cations, is higher than the H acidity of the diazohydroxide.The high equilibrium concentration and the high decomposition rate of this product, the presence of which was demonstrated experimentally, give rise to the extremely low stability of aqueous alkaline solutions of the phenylazobenzenediazonium salt.
