The sodium salt of 2-quinizarinsulfonic acid (NaQ) forms a complex with Al'+ that absorbs radiation strongly at 560 nm.32
(a) Use the data from Owens and Yoe's paper to find the formula of the complex. In all solutions, CAI = 3.7 X 10-5 M, and all measurements were made in 1.00-cm cells.
(b) Find the molar absorptivity of the complex.
