Consider the titration of 100.0 mL of 0.100 M NaOH with 1.00 M HBr. Find the pH at the following volumes of acid added.
| Va = 0 mL | |
| Va = 1.0 mL | |
| Va = 5.0 mL | |
| Va = 9.0 mL | |
| Va = 9.9 mL | |
| Va = 10.0 mL | |
| Va = 10.1 mL | |
| Va = 12.0 mL |
Make a graph of pH versus Va = 0, 1.0, 5.0,
9.0, 9.9, 10.0, 10.1, and 12.0 mL.
