Question

Spectroscopic data for three organic dyes, A, B, and C, are shown in the table. A solution containing a mixture of these three dyes in a 1.000

Spectroscopic data for three organic dyes, A, B, and C, are shown in the table. A solution containing a mixture of these three dyes in a 1.000??cm cuvet had absorbances of 0.5221 at 450 nm, 0.3925 at 480 nm and 0.6012 at 520 nm. Find the concentrations of the three dyes in the solutions. For each solution, the zero is set with a blank. Wavelength (nm) 450 480 520 Ea M-1cm-1 3200 5900 27500 Eb M-1cm-1 10900 9400 12200 Ec M-1cm-1 19300 10100 3500 find [A], [B], and [C].

Explanation / Answer

Ca = 1.12 * 10-5

Cb = 2 * 10-5

Cc = 1.34 * 10-5
