9.
Describe three ways to prepare a 1.00 M acetic acid/sodium acetate buffer solution with a
pH
=
4.00.
10.
You have available to you 1.50 M solutions of acetic acid, sodium acetate, sodium hydroxide, and
hydrochloric acid. How can you make 50 mL of each of the buffers described in the preceding problem?
11.
How can you make a 1.0 M buffer solution with a
pH
=
3.30
?
12.
You are planning to carry out a reaction that produces protons. In order for the reaction to take place at
constant pH, it will be carried in a solution buffered at
pH
=
4.2.
Would it be better to use a formic acid/
formate buffer or an acetic acid/acetate buffer?
