Chapter 6: Chemical Reactions
 Identify and write equations for acid–
base reactions.
 Acid–base reactions are reactions that
form water upon mixing of an acid and a
base.
 No evidence of a chemical reaction is
observable.
 The reactants and other products are
soluble in water.
 Arrhenius acids: substances that
produces H+ ions when dissolved in
water.
 Arrhenius bases: substances that
produces OH- ions when dissolved in
water.
 Acid–base reactions (also called
neutralization reactions) generally form
water and an ionic compound, called a
salt, that usually remains dissolved in
the solution.
 HBr(aq) + NaOH(aq) → H2O(l) + NaBr(aq)
 Without spectator ions:
H+(aq) + OH–(aq) → H2O(l)
 The net ionic equation for many acid–
base reactions is as follows:
 H+(aq) + OH− (aq) → H2O(l)

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.

When benzoic acid (HC7H5O2) and
magnesium hydroxide are mixed, water and
magnesium benzoate are produced.
 Aqueous nitric acid reacts with aqueous
potassium hydroxide.
