The magnesium and calcium ions present in seawater ([Mg2+] = 0.059 M and [Ca2+] = 0.011 M) can be separated by selective precipitation with KOH.

If the concentration of Mg2+ in the solution were 0.019M , what minimum [OH?] triggers precipitation of the Mg2+ ion? (Ksp=2.0610?13


1. Sodium hydroxide is added to a CSTR to remove magnesium ion from an extracted groundwater stream (Q = 150 gpm). The temperature of the reactor is depat at 25C and pH = 11. Ksp for Mg(OH)2 is 9 x 10-12. The influent Mg2+ concentration is 100 mg/L. Estimate:

The Mg2+ in the treated effluent (mg/L).

Rate of Mg(OH)2 produced (lb/day).
