Aluminum has been implicated as a neurotoxic agent for Alzheimer’s patients and is known as harmful for renal failure patients. In 1985, the medical community recommended that no more than 10 mg/L Al3+ be present in drinking water used for dialysis patients. At what pH is the maximum Al3+ concentration equal to 10 mg/L, assuming that the only source of Al3+ is Al(OH)3? How does this compare with the allowable pH of drinking water of 7.8; would we expect to observe this concentration in drinking water?
