The sodium salt of 2-quinizarinsulfonic acid (NaQ) forms a
complex with Al31 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, cAl 5 3.7 10-5
M, and all measurements were made in 1.00-cm cells. (b) Find the molar
absorptivity of the complex.
