Question

Write the complete ionic equation for the reaction of magnesium phosphate with lead (II) nitrate. Include which ions will be aqueous and which compound will precipitate. (Valences: Mg=+2, PO4=-3, Pb=+2, NO3=-1)

Someone may be under the false impression that Mg3(PO4)2 is soluble but it isn't. Pb3(PO4)2 is insoluble, too, and which predominates depends upon the solubility product of each.
