Net Ionic: Ag
(aq) + Cl
(aq) AgCl (s) (precipitate)
In a Net Ionic the spectator ions are left out
Think in terms of ions in solution and not just formulas as written
+
Na
(aq) means aqueous or in water
+
If aq not given Na
can still assume in water solution if discussing solutions
but for something like NaCl must specify NaCl(s) or NaCl(aq)
Metathesis double displacement
Two compounds in solution and exchange of cations
Actual change:
NaCl + AgNO
AgCl + NaNO

Net Ionic Reaction: Ag+ (aq) + Cl- (aq) AgCl (s)
OR no real change
KCl + NaNO
KNO

Reaction will occur if:
1. Precipitate formed
2. Weak electrolyte formed
3. Gas formed
These will have the effect if remove product the equilibrium shifts to the right and more product
is formed (LeChatlier’s Principle)
