1. (8 pts) Consider if the initial unknown acid solution used in this experiment started out more dilute. Predict any differences you would expect to see in the titration curve ‐ clearly identify what changes, if any, are expected for:
 initial pH
 pH at the half‐equivalence point
 NaOH volume needed to reach the equivalence point
 pH at the equivalence poin

Answer:

The answers are in the explanation

Explanation:

- Initial pH: An acid solution more dilute has a higher pH because concentration of H⁺ decreases.

- pH at the half‐equivalence point: In a titration curve. The pH at the half-equivalence point will be higher because the initial pH is higher and the equivalence point pH is the same.

- NaOH volume needed to reach the equivalence point: As the diulte solution has a higher pH, the NaOH volume you need is lower than original solution.

- pH at the equivalence point: The pH at the equivalence point will be always the same (pH = 7,0). Because is the pH where the total H⁺ of the acid were consumed.

I hope it helps!
