If a solution of sodium phosphate, Na3PO4, is poured into seawater, precipitates of calcium phosphate and magnesium phosphate are formed. (Magnesium and calcium ions are among the principle ions found in seawater.) Write net ionic reactions for the reactions. Include physical states in your answers.
Formation of calcium phosphate
Formation of magnesium phosphate
3Ca^2+(aq) + 2PO4^3-(aq) ==> Ca3(PO4)2(s)
Mg3(PO4)2 is done the same way.
