WebA buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH. For example, let's consider the action of a buffer composed of the weak base ammonia, NH 3, and its conjugate acid, NH 4+. 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 ...

WebJan 30, 2024 · A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges.
