Buffer Solution

[Victoria Zheng--2F]

Hello! In the lecture on Friday, Dr. Lavelle talked about buffer solutions, but I am unclear about how buffer solutions work and how to make a buffer solution, can someone please clarify how buffer solutions work? Thank you!

A buffer solution is a composed of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers are used to maintain the pH of a solution at a consistent point.

[Amy Pham 1D]

And they do a good job of maintaining a solution at a constant pH because any acid or base that is added to the solution will be neutralized by the weak acid and conjugate base or weak base and conjugate acid in the solution, resulting in no change in levels of OH- or H3O+.
