Product description
55th century The test solution contains an intensely colored complex compound of the metal cation M2 with an organic reagent with a concentration of the metal cation C(M2)=5.00*10-5 mol/l. Based on the results of measuring the optical density A of the test solution at different wavelengths λ in a cell with an absorbing layer thickness of 2.00 cm (option a), 1.00 cm (options b, c, d), plot the absorption spectrum of this complex compound in the coordinates A-λ, nm.
Choose an analytical wavelength for determining the metal cation by the spectrophotometric method by the light absorption of its complex compound. At the chosen wavelength, calculate the molar extinction ratio of the complex compound in solution in terms of the metal cation.
