Al^3+ forms a complex ALSO4+ in the presence of sulfate...
Al^3+ + SO4^2- = AlSO4+
with Kstab = 10^3.01
Question: 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)
Someone responded and said to look at a phase diagram but the problem is not set up for that...the answer is 3 ppm but need help with the set-up. The textbook offered very little guidance with complexes. Can someone please help. I have another problem similiar to this one but can't do that one either until I can get some feedback on this one...please...
