Understanding how to prepare the buffer solution, or simply a buffer solution, is a core laboratory skill in chemistry, biochemistry, medicine, and environmental science. In real terms, a buffer solution is a liquid mixture that resists large changes in pH when small amounts of acid or base are added. This stability is essential for enzyme reactions, cell culture, analytical assays, pharmaceutical testing, and many industrial processes. In this guide, you will learn the principles behind buffer preparation, the correct calculations, the step-by-step procedure, common mistakes to avoid, and practical tips that help you produce a reliable, reproducible solution.
What Is a Buffer Solution?
A buffer solution usually contains a **weak acid and its conjugate base
