4. Cr(VI) and Mn(VII) were determined photometrically from the same solution in a cuvette with l = 1.0 cm, at λ1 = 550 nm and λ2 = 430 nm. The molar coefficients are respectively equal to:
for chromium ελ,1 = 0.0; ελ,2 = 220;
for manganese ελ,1 = 2100; ελ,2 = 500.
The transmission (T,%) of the solution at λ1 turned out to be 41%, and at λ2 = 26%. Calculate the (content) concentration of chromium and manganese in the photometric solution.
