NET IONIC:

WILL SOMETHING PRECIPITATE? Always soluble (aq): ionic compounds containing… group 1 alkali metals, ammonium, nitrate, chlorate Soluble EXCEPT: chloride = soluble, unless containing Pb, Ag, Hg “the big three” sulfate = soluble, unless containing Pb, Ag, Hg, Ca, Sr, Ba NOT soluble (unless meets conditions above): carbonate, phosphate, chromate, sulfide, hydroxide
