7.
How does the titration curve of a weak acid and a strong base differ from the titration curve of a strong acid and a strong base?
1. The pH value changes more readily in the titration curve of the strong acid and the strong base
2. The pH value changes equally for each of the titration curves
3. The pH value changes more readily in the titration curve of a weak acid and a strong base
4. The pH value changes only in the presence of a buffer
8.

2. neutralization point
3. buffering region
4. equivalence point
9.
When a strong base is titrated with a certain kind of acid, the titration curve is determined to have three equivalence points. Name ONE possible strong base that could have been added to result in this titration curve.

10.
