Abstract

Complex formation between cupric ion and o-phenylenediamine has been studied by means of spectrophotometric and potentiometric measurements. The results obtained by the two methods are in good agreement. For the formation constants of the two in aqueous solution existing complexes Cu(II)L and Cu(II)L2 the values log K1 = 4,43 ± 0,05 and log K2 = 3,75 ± 0,03 (T = 25°C, I= 0,4) have been established.
