Al3+ forms a complex Al (SO4)+ with Kstab = 103.01 in the presence of sulfate.
Write down a balanced reaction for the above reaction determine the number of ppm of Al (total) would be in equilibrium with gibbsite at pH 5 and 25°C in the presence of 10-3m of(SO4)2-? Suppose the activities =concentrations and this is the only complex that forms.
