    • - showed, on starting the addition of anion, an increase in absorbance between 400 and 441 nm and, less significantly, at 609 nm. The system then became cloudy due to the precipitation of the anion added. By adding more anion, the system became transparent again, but the absorbance value at 609 nm did not surpass 0.120.
