What is Buffer?
A buffer is a solution that resists drastic pH changes when an acid or base is added to it. This is essential for chemical and biological processes that require specific and stable pH ranges.
Buffers are most often formed by mixing a weak acid and its conjugate base with water. The pKa values of the acid and base determine how wide the pH range can be for a buffer solution.
A buffer solution is an aqueous solution that can resist changes to its pH on the addition of small amounts of acid or base. A buffer solution is often made of a weak acid and its conjugate base, or a weak base and its conjugate acid.
Buffer solutions have a pH that is mainly determined by the ratio of acid to salt, which can be changed with the addition of additional acids and bases. Examples of potential buffers include phosphoric, citric, or boric acids and their salts.
Buffers are important to living organisms because most biochemical processes occur only at specific pH values. This is why blood has a normal pH range of 7.35 to 7.45, and why natural buffer systems in our bodies act to maintain this level.
A buffer is a chemical compound that resists change in pH when a small amount of acid or base is added. This is important in chemistry because many biochemical reactions happen at a constant pH.
For example, if you add acetic acid to an acetate buffer solution, the incoming acetic acid donates a proton to the acetate ions and becomes acetic acid and water, which keeps the pH stable without changing dramatically.
Buffers are very important in custom manufacturing because they help protect your production from unforeseen events and allow you to deliver jobs on time. Buffers are also used for instrument calibration, but these applications are usually done at high concentrations.
A buffer is an aqueous solution that resists changes in pH when a weak acid or base is added to it. This system keeps the pH from rising and prevents drastic changes in it, which is important for keeping organisms and their cells alive.
A simple buffer can be made by mixing a weak base and its conjugate acid in a solution of water. The acid neutralizes the hydroxide ions, while the base consumes the hydronium ions (which are already in the buffer).
Another example is a buffer made from ammonia and its conjugate acid, ammonium ion. When a strong acid is added, ammonia consumes the extra hydrogen ions that were produced by HCl (another strong acid).
These reactions do not have a large effect on the overall pH of the buffer. However, they do allow the buffer to keep its moderate pH when it is diluted or changed by adding acid or base. This is called its ‘buffer capacity’.

Buffers are used to keep a solution’s pH stable. This is essential for many chemical and biological processes that occur within a narrow pH range.
For example, blood plasma contains a buffer of carbonic acid and bicarbonate to maintain a pH of about 7.4. This ensures that enzymes work correctly.
In industry, buffer solutions are used for fermentation processes and in setting the appropriate conditions for dyeing fabrics. They are also used in chemical analyses and syntheses, and for the calibration of pH meters.
In biopharmaceutical research, buffers are used to control the pH of drug formulations before they are tested for aqueous solubility. This prevents the drug from being hydrolyzed. It also reduces the rate of oxidation, which can damage the drug.
