Which of the following conditions is/are met at the equivalence point of the titration of a monoprotic weak base with a strong acid?
| 1. | The moles of acid added from the buret equals the initial moles of weak base. | |
| 2. | The volume of acid added from the buret must equal the volume of base titrated. | |
| 3. | The pH of the solution is less than 7.00. |
Homework Answers
Correct answers are 1 and 3
titration happens when the number of moles of acid equals the number of moles of base.
If you are titrating a weak base with a strong acid then you can expect to have a ph less than 7

The pH at the equivalence point of a titration of an unknown monoprotic substance with a strong titrant is determined to be 6.63. Based on this pH value, explain whether the unknown substance is a strong acid, strong base, weak acid, or weak base. A chemist wants to perform a reaction at pH = 8.3 so they attempt to make a buffered solution. For this buffer, the chemist dissolves 12.5 moles of methylammonium, CH3NH3+, (Ka = 2.3 x 10–11) and...
