Net Ionic Equations

Chemical equation for a reaction which lists only those ions participating in the reaction and excludes spectator ions.

• Q: What precipitate (solid) will form? • A: Fe(OH)3 (s)

• Q: What are the other ions doing in the final beaker?• A: Floating in the solution and not reacting.

• Write out the overall balanced reaction:• FeCl3 + 3 NaOH Fe(OH)3 (s) + 3 NaCl

• Complete Ionic Reaction:• Fe3+ + 3 Cl- + 3 Na+ + 3 OH- Fe(OH)3 + 3 Na+ + 3 Cl-

• Net Ionic Reaction:• Fe3+ + 3 OH- Fe(OH)3

• Q: What precipitate (solid) will form?• A: AgCl (s)

• Q: What are the spectator ions doing in the final beaker?

• A: Floating in the solution and not reacting.

• Write out the overall balanced reaction:• KCl + AgNO3 AgCl(s) + KNO3

• Complete Ionic Reaction:• K+ + Cl- + Ag+ + NO3
