   3## Precipitation reactions
   4
   5- water cannot dissociate ionic lattice structure (e.g. NaCl and other salts)
   6- aqueous ions combine to form a new compound
   7- occurs when concentration exceeds solubility (precipitate = insoluble solid)
   8- all group 1 ions are soluble
   9
  10e.g. NaCl(aq) + AgNO3(aq) -> NaNO3(aq) + AgCl(s)
