I've posted this question now three times and no one has responded. I first posted it Sunday 2/11 at 1 pm. Meanwhile, other questions are being answered. Can someone please help...

Al^3+ forms a complex ALSO4+ in the presence of sulfate...
Al^3+ + SO4^2- = AlSO4+

with Kstab = 10^3.01

How many ppm Al(total) would be in equilibrium with gibbsite at pH 4 and 25 degrees celsius in the presence of 10^3- m
SO4^2- (consider only this one complex and assume activities = concentrations)

Am having a tough time with complexes, hope you can help. Thanks.

why not look again at the phase diagram and stop cheating by trying to get someone to do your coursework for you
