Pd(II) and Au(II) can be determined simultaneously by the reaction with methiomeprazine (C 19 H 24 N 2 S 2 ). The maximum absorption for Pd occurs at 480 nm, while for the Au complex it is at 635 nm. A sample of 25 mL was treated with excess of the complexant and then diluted to 50.0 mL. Calculate the molar concentrations of Pd(II) and Au(II) in the sample. The data are found in the table below and the bucket used was 1.0 cm.
