Chemistry: Solubility ?
posted by Amy~ .
There are solubility rules and for soluble compounds some have exceptions next to them.
Such as Halides are soluble
Exception: Ag, Hg, Pb
What does it mean by exception?
For Halides would it be, that if the compound was AgCI it wouldn't be soluble?
Right. AgCl, Hg2Cl2, and PbCl2 are not soluble. The other chlorides are. For whatever it's worth, PbCl2 is soluble in hot water but not cold water.
