- all nitrates are water soluble
- All salts of the ammonium ion (NH4+) are water soluble
- All carbonates (CO32-), phosphates (PO43-) and Sulfites (SO32-) are insoluble, except when complexed with alkali metals or ammonium ions
- All chlorides, bromides, and iodides are water soluble, except when they contain Ag+, Pb2+, and Hg2+

Definition
Any solute whose solution conducts electricity. Can be strong or weak, depending on whether they dissociate completely or only partially (like acids and bases). Strong acids/bases would be strong electrolytes. (weak a/b=weak electrolyte) -Must be soluble and produce charge as result of dissolution -Sugar is not-- dissociates in water but does not create a charge. HF= very weak; creates charge but barely dissociates. HCl=strong electrolyte |
