  1. chemistry

  2. 11.3 Reactions in Aqueous Solution • Structures in limestone caverns are formed when carbon dioxide converts calcium hydrogen carbonate into calcium carbonate. The calcium carbonate precipitates and forms dramatic stalactites and stalagmites. You will learn to predict the formation of precipitates and write equations to describe the reactions that produce them.

  3. 11.3 Net Ionic Equations • Net Ionic Equations • What does a net ionic equation show?

  4. 11.3 Net Ionic Equations • A complete ionic equationis an equation that shows dissolved ionic compounds as dissociated free ions.

  5. 11.3 Net Ionic Equations • An ion that appears on both sides of an equation and is not directly involved in the reaction is called a spectator ion. • The net ionic equationis an equation for a reaction in solution that shows only those particles that are directly involved in the chemical change.

  6. 11.3 Net Ionic Equations • A net ionic equation shows only those particles involved in the reaction and is balanced with respect to both mass and charge.

  7. 11.3 Net Ionic Equations • Sodium ions and nitrate ions are not changed during the chemical reaction of silver nitrate and sodium chloride so the net ionic equation is

  9. 11.3 Predicting the Formation of a Precipitate • Predicting the Formation of a Precipitate • How can you predict the formation of a precipitate in a double-replacement reaction?

  10. 11.3 Predicting the Formation of a Precipitate • You can predict the formation of a precipitate by using the general rules for solubility of ionic compounds.

  11. 11.3 Predicting the Formation of a Precipitate

  12. 11.3 Predicting the Formation of a Precipitate • Will a precipitate form when a sodium carbonate solution is mixed with a barium nitrate solution?

  13. 11.3 Predicting the Formation of a Precipitate • Sodium nitrate is soluble but barium carbonate is insoluble. The net ionic equation is

  15. 11.3 Section Quiz. • 1. Identify the correct net ionic equation for the following reaction and the spectator ion, if there is one. • FeO(s) + 2HClO4(aq)  H2O(l) + Fe(ClO4)2(aq) • FeO(s) + 2H+(aq) + 2ClO4-(aq)  H2O(l) + Fe2+(aq) + 2ClO4-(aq); ClO4- no spectator ion • FeO(s) + 2H+(aq) + 2ClO4-(aq)  H2O(l) + Fe2+(aq) + 2ClO4-(aq); ClO4- is a spectator ion • FeO(s) + 2H+(aq)  H2O(l) + Fe2+(aq); ClO4- • FeO(s) + 2HClO4(aq)  H2O(l) + Fe(ClO4)2(aq); no spectator ion

  16. 11.3 Section Quiz. • 2. Which one of the following products of double-replacement reactions would NOT form a precipitate? • AgCl • PbSO4 • Mg(OH)2 • Mo(NO3)2

  17. 11.3 Section Quiz • 3. Which reaction will NOT produce a precipitate from aqueous solution? • Hg2(NO3)2 + KCl • FeSO4 + Ba(OH)2 • Pb(NO3)2 + Na2CO3 • NaBr + Al2(SO4)2
