  1. Double Double Replacement Reactions Written as Net Ionic Equations

  2. Chemistry Joke Q: What is NaCl(aq) + NaCl(aq) C C C C C C C ? A: Saline, Saline, Over the Seven Cs!

  3. What happens when you put AgNO3 and NaCl in water?

  4. NaCl AgNO3

  5. NaCl AgNO3

  6. AgNO3 NaCl

  7. AgNO3 NaCl

  8. AgNO3 NaCl

  9. AgNO3 NaCl

  10. AgNO3 NaCl

  11. Na Cl Ag NO3

  12. In the water, the compounds separate into their ions. Ag+ NO3- Cl- Na+

  13. Ag+ Cl- Na+ NO3-

  14. Ag+ Cl- NO3- Na+

  15. NO3- Ag+ Na+ Cl-

  16. NO3- Na+ Ag+ Cl-

  17. NO3- Na+ Ag+ Cl-

  18. NO3- Na+ Cl- Ag+

  19. Na+ NO3- Cl- Ag+

  20. Na+ NO3- Cl- Ag+

  21. Na+ NO3- Ag+ Cl-

  22. Na+ NO3- Ag+ Cl-

  23. Na+ NO3- Ag+ Cl-

  24. Na+ NO3- Ag+ Cl-

  25. NO3- Na+ AgCl

  26. Na+ NO3- AgCl

  27. Na+ NO3- AgCl

  28. Insoluble combinations of ions will form precipitates. Na+ NO3- AgCl(s) precipitate AgCl

  29. Here is the complete equation. AgNO3 (aq) + NaCl(aq) AgCl(s) + NaNO3(aq) Now we will write it as an ionic eqn. Everything (aq) gets separated and written as ions!

  30. Let’s look at the reaction again: AgNO3 NaCl

  31. Na Cl Ag NO3

  32. Ag+ NO3- Cl- Na+

  33. Ag+ Cl- Na+ NO3-

  34. Ag+ Cl- NO3- Na+

  35. NO3- Ag+ Na+ Cl-

  36. NO3- Na+ Ag+ Cl-

  37. NO3- Na+ Ag+ Cl-

  38. NO3- Na+ Cl- Ag+

  39. Na+ NO3- Cl- Ag+

  40. Na+ NO3- Cl- Ag+

  41. Na+ NO3- Ag+ Cl-

  42. Na+ NO3- Ag+ Cl-

  43. Na+ NO3- Ag+ Cl-

  44. Na+ NO3- Ag+ Cl- Reaction

  45. Na+ NO3- AgCl

  46. No Reaction Na+ NO3- AgCl

  47. These ions do not participate in the reaction. They are called SPECTATOR IONS. Na+ NO3- AgCl

  48. The netionic eqn comes from the complete ionic eqn. Any ion that appears on both sides of the arrow is eliminated. NO3- and Na+ are not participating in the actual reaction. Ag+ and Cl- are reacting to form AgCl (s).

  49. Net Ionic Equation doesn’t include those Spectator Ions!

  50. Chemistry Joke Q: If you’re not part of the solution… A: You’re part of the precipitate!
