1. Chapter 6: Chemical Reactions

2.  Identify and write equations for acid– base reactions.

3.  Acid–base reactions are reactions that form water upon mixing of an acid and a base.

4.  No evidence of a chemical reaction is observable.  The reactants and other products are soluble in water.

5.  Arrhenius acids: substances that produces H + ions when dissolved in water.

7.  Arrhenius bases: substances that produces OH - ions when dissolved in water.

9.  Acid–base reactions (also called neutralization reactions) generally form water and an ionic compound, called a salt, that usually remains dissolved in the solution.

10.  HBr (aq) + NaOH (aq) → H 2 O (l) + NaBr (aq)  Without spectator ions: H + (aq) + OH – (aq) → H 2 O(l)

11.  The net ionic equation for many acid– base reactions is as follows:  H + (aq) + OH − (aq) → H 2 O(l)

12.  Write chemical, complete ionic, and net ionic equations for each of the following reactions that produce water.  Mixing sulfuric acid and aqueous potassium hydroxide produces water and aqueous potassium sulfate.

13.  When benzoic acid (HC 7 H 5 O 2 ) and magnesium hydroxide are mixed, water and magnesium benzoate are produced.

14.  Aqueous nitric acid reacts with aqueous potassium hydroxide.
