Product description
- The molar absorption coefficient of the complex of gallium with xylenol orange is 32900 at 545 nm. Determine the concentration of gallium in the solution if the relative optical density of the test solution, measured in a cuvette with l=10 mm, in relation to the reference solution containing 5.3×10-5 g/l of gallium, corresponds to 0.41.
