For which of the following solutions must we consider the autoionization of water when calculating the pH?
| a. |
0.1 M HCl |
|
| b. |
0.00080 g of NaOH in 0.5 L of solution |
|
| c. |
3 X10-8 M HNO3 |
|
| d. |
0.0245 M KNO3 |
Homework Answers
Auto ionization is taken in to consideration for very dilute
solutions. From the given options
a) 0.1 M HCl
b) 0.00080 g NaOH in 0.5 L soltion, concentration = 4 x
10-6 M
c) 3 x 10-8 M HNO3
d) 0.0245 M KNO3
Option b, c are very dilute solutions and
we need to consider auto ionization while calculating the
pH.

In this experiment you will be measuring pH for several
different solutions. A pH probe will be used rather than pH paper
as it will be more accurate.
You will be testing the pH of six solutions: deionized water,
0.1 M HCl, 0.1 M HCH3COO, 0.1 M NaCH3COO, 0.1
M NaOH, and a buffer made by mixing equal parts of
HCH3COO and NaCH3COO.
