Buffer solution example
WebAug 19, 2024 · Buffer solutions resist changes in pH. When a small amount of base or acid is added to a solution containing a buffer, it tries to minimize the change in pH as much as possible. For example, the pH of pure water is 7.0. When an acid or base gets added to water, it turns into an acidic or a basic solution. However, water + buffer solutions have ... WebThe example we're gonna look at is going to be using an acetic acid buffer. So acetic acid is CH three COOH. And we're gonna abbreviate that in this talk using HA. And this is an aqueous solution and that is reversibly reacting to form H plus ion and CH three COO minus, or acetate. And so we're gonna abbreviate acetate in this talk as A minus.
