A) Aluminum ion (Al3+) is present in an industrial wastewater at 3 mg/L. The treatment facility wants to precipitate out the aluminum until there is only 0.2 mg/L remaining. What pH is required to acheive this aluminum ion concentration?
B) what mass of AlOH3 is produced if we treat 10,000 L?
C) List two compounds that could be used to raise the pH to this level.
D) Finally, what species or compound is typically used to re-acidify a water after its pH has been raised to precipitate out metals?
