At a wastewater treatment plant, FeCl3(s) is added to remove excess phosphate from the effluent. Assume the following reactions occur: FeCl3 ---> Fe3+ + 3Cl- FePO4 ---> Fe3+ + PO4 3␣ The equilibrium constant for the second reaction is Ksp 1⁄4. What concentration of Fe3+ is needed to maintain the phosphate concentration below the limit of 1 mg P/L?
