Zinc(II) and the ligand L form a 1:1 complex that absorbs
strongly at 600 nm. As long as the molar concentration of L exceeds that of
zinc(II) by a factor of 5, the absorbance depends only on the cation
concentration. Neither zinc(II) nor L absorbs at 600 nm. A solution that is 1.59
10-4 M in zinc(II) and
1.00 10-3 M in L has an
absorbance of 0.352 in a 1.00-cm cell at 600 nm. Calculate
(a) the percent transmittance of this solution.
(b) the percent transmittance of this solution in a 2.50-cm
(c) the molar absorptivity of the complex.
