1. If a 0.10 M solution of an acid has a pH of 4.5, using your data and graph from goal 2, what would be the predicted pH of a 0.10 M solution of the conjugate and why?
| Goal #2 | ||
| Conjugate Acid Base Pair | pH of Acid | pH of Base |
| HCl/Cl- | 1.60 | 4.94 |
| Formic Acid/Formate | 2.49 | 6.72 |
| Propionic Acid/Propanoate | 3.21 | 7.67 |
| Ammonium/Ammonia | 5.89 | 11.10 |
this is the data from goal 2
Homework Answers
