1 Slide 1 of 21 chemistry

2 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Slide 2 of 21 Net Ionic Equations What does a net ionic equation show? 11.3

3 Slide 3 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Net Ionic Equations A complete ionic equation is an equation that shows dissolved ionic compounds as dissociated free ions. 11.3

4 Slide 4 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > 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 equation is an equation for a reaction in solution that shows only those particles that are directly involved in the chemical change. 11.3

5 © Copyright Pearson Prentice Hall Slide 5 of 21 Reactions in Aqueous Solution > 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. 11.3

6 Slide 6 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > 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 11.3

11 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Slide 11 of 21 Predicting the Formation of a Precipitate How can you predict the formation of a precipitate in a double-replacement reaction? 11.3

12 Slide 12 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Predicting the Formation of a Precipitate You can predict the formation of a precipitate by using the general rules for solubility of ionic compounds. 11.3

13 Slide 13 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Predicting the Formation of a Precipitate 11.3

14 Slide 14 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Predicting the Formation of a Precipitate Will a precipitate form when a sodium carbonate solution is mixed with a barium nitrate solution? 11.3

15 Slide 15 of 21 © Copyright Pearson Prentice Hall Reactions in Aqueous Solution > Predicting the Formation of a Precipitate Sodium nitrate is soluble but barium carbonate is insoluble. The net ionic equation is 11.3
