● Monoprotic acid:
example:
● Diprotic acid:
example:
●Triprotic acid:

3) Give the Arrhenius definition of an ACID with an example.
4) Give the Arrhenius definition of a BASE with an example.
5) Give the Bronsted-Lowry definition of an ACID with an example.
6) Give the Bronsted-Lowry definition of a BASE with an example.
7) Define a conjugate acid and a conjugate base. What is a conjugate acid-base pair? Give examples of
each.
● Conjugate acid:
example:
● Conjugate base:
example:
●Conjugate acid-base pair:
example:
8) What does AMPHOTERIC mean? Provide an example.
9) using the table (19.3) on page 651, tell whether you expect each substance listed to behave as an
acid or a base, and give its conjugate partner.
Acid or Base
Conjugate Pair
● HCl
● OH● H2SO4
● NH4+
● Cl-
10) Using the table (19.3) on page 651, which substance is found as both an acid and a base? What is
its conjugate pair as an acid, and what is its conjugate pair as a base?
11) Identify each of the following reactants as either an acid or a base. Also label the two products as
conjugate acid or conjugate base.

conjugate acid, and conjugate base.
b) Write the equation for the ionization of nitric acid (HNO3) with water. Label the acid, base, conjugate
acid, and conjugate base.
c) Write the equation for the ionization of CO32- with water. Label the acid, base, conjugate acid, and
conjugate base.
