Buffer Region on a pH Curve

Postby Alex Nguyen 3I » Fri Dec 04, 2015 2:23 pm

If you had to make a pH curve for a titration, how would you know when the buffer region ends?

The buffer region ends when the pH starts to change significantly.

The buffer region of the pH curve is the region in which lots of volume of the titrant is added with little change to the pH of the titrant-sample solution; on the graph, it appears as a relatively horizontal (flat) portion of the curve.
