Question

What would happen to the final answer if you forgot to add water to test tube #1 but used 20.00mL as your total volume in your calculation?

(Q2) The calculations are done assuming that OH- added is reacting completely. What would happen to the final result if not all OH- was used up?

Explanation / Answer

Q1.The distilled water you add on this erlenmeyer will change its volume, but won't change the number of mols of acid inside it, neither the initial volume you added of the acid solution. Sometimes it's even recommended that you add some water to make the color change more visible.

Q2. After the equivalence point, the solution will contain two bases: the conjugate base of the acid and the strong base of the titrant. However, the base of the titrant is stronger than the conjugate base of the acid. Therefore, the pH in this region is controlled by the strong base.therefore a slight increase in the pH of the solution will be increased.
