Detection and spectrophotometric determination of copper(III) with p-anisidine.
Copper(III) solutions are found to give an instantaneous stable pink-coloured product with 0.2% aqueous p-anisidine in the presence of 0.03N acetic acid. The wavelength of maximum absorption is 533 nm and obeys Beer's law up to 0.89408 g copper(III). It is also recommended as a spot test for copper(III).
