You have 225 mL of an 0.43 M acetic acid solution. What volume
(V) of 1.10 M NaOH solution must you add in order to prepare an
acetate buffer of pH = 4.23? (The pKa of acetic acid is 4.76.)
You have 525 mL of an 0.15 M acetic acid solution. What volume
(V) of 2.00 M NaOH solution must you add in order to prepare an
acetate buffer of pH = 5.32? (The pKa of acetic acid is 4.76.)
You have 625 mL of an 0.23 M acetic acid solution. What volume
(V) of 2.10 M NaOH solution must you add in order to prepare an
acetate buffer of pH = 5.03? (The pKa of acetic acid is 4.76.)
1. What is the pH of a solution with 15 mL of 0.5 M acetic acid
and 15 mL of 0.5 M sodium acetate in solution.
2. What is the pH if we were to take 5 mL of the above solution
and add it to 25 mL of water.
Please explain and work all steps.
A 25.0-mL solution of 0.100 M acetic acid is titrated with a
0.200 M KOH solution. Calculate the pH after the following
additions of the KOH solution:
a) 0.0 mL b) 5.0 mL c) 10.0 mL d) 12.5 mL e) 15.0 mL
A 25.0 mL sample of a 0.110 M solution of acetic acid is
titrated with a 0.138 M solution of NaOH. Calculate the pH of the
titration mixture after 10.0, 20.0, and 30.0 mL of base have been
added. The Ka for acetic acid is 1.76x10^-5.
5. In the titration of 15.00 mL of a 0.1000 M acetic acid
solution by a 0.1000 M NaOH solution, find the pH of the solution
being titrated when
a) 0.00 mL of NaOH has been added
b) 5.00 mL of NaOH has been added
c) 7.50 mL of NaOH has been added
d) 14.90 mL of NaOH has been added
e) 15.00 mL of NaOH has been added
f) 30.00 mL of NaOH has been added
In an acid base titration experiment, 50.0 ml of a 0.0500 m
solution of acetic acid ( ka =7.5 x 10^-5) was titrated with a
0.0500 M solution of NaOH at 25 C. The system will acquire this pH
after addition of 20.00 mL of the titrant:
