Worksheet: Neutralization and Titration
1. Give the word equation for the neutralization reaction of an acid and a base.
acid + base  water + salt
2. Complete these equations:
HCl + LiOH 
2HC2H3O2
H2O + LiCl
+ Mg(OH)2  2 H2O + Mg(C2H3O2)2
titration
3. A _______________
is a laboratory method used to determine the
base
concentration of an acid or a _______________
in solution by performing a
neutralization
_______________
reaction with a standard solution.
4. At the ______________
of the titration, the indicator changes color, which
endpoint
H+
indicates neutralization. Once neutralized, moles of _______________
and
OH
moles of _______________ are equal.
5. In a titration of HCl with NaOH, 100.0 mL of the base was required to
neutralize 20.0 mL of 5.0 M HCl. What is the molarity of the NaOH? (Be sure
to write the neutralization reaction.)
moles H +
moles OH !
( M A )(V A ) =
( M B )(VB )
1 moleA
1 moleB
HCl + NaOH  H2O + NaCl
1moles H +
1moles OH !
(5.0 M )(20.0mL) =
( M B )(100.0mL)
1 moleA
1 moleB
M B = 1.0 M NaOH
6. In a titration of H2SO4 with NaOH, 60.0 mL of 0.020 M NaOH was needed to
neutralize 15.0 mL of H2SO4. What is the molarity of the acid? (Be sure to
write the neutralization reaction.)
H2SO4 + 2NaOH  2H2O + Na2SO4
2moles H +
1moles OH !
( M A )(15.0mL) =
(0.020 M )(60.0mL)
1 moleA
1 moleB
M A = 0.040 M H 2 SO4
7. If 10.0 mL of 0.300 M KOH are required to neutralize 30.0 mL of gastric juice
(HCl), what is the molarity of the gastric juice?
HCl + KOH  H2O + KCl
1moles H +
1moles OH !
( M A )(30.0mL) =
(0.300 M )(10.0mL)
1 moleA
1 moleB
