Buffer solution - Wikipedia

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an acid or a base aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. In nature, the… 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 ...
