Reactions in Aqueous Solutions

• Aqueous - in solution or in water

AgNO3(aq) NaCl(aq) AgCl(s)
NaNO3(aq)

• Complete Ionic Reaction

- an equation that show dissolved ionic compounds
as free ions
Ag NO3- Na Cl- Ag
Cl- Na NO3-

• Spectator Ions

- Ions that are not directly involved in the
reaction
2

• Net Ionic Reaction

- an equation that shows only the particles that
take part in the reaction
Ag NO3- Na Cl- AgCl
