Buffer solutions

Buffer solutions are substances the pH of which does not change when small amounts of strong acids or bases are added to them. Their pH remains unchanged even when the preparation is diluted with water. The success of many reactions depends on the correct concentration of ions used in the solutions – this is why it is important to use precise buffering substances that allow pH regulation.

What does the buffer solution consist of? Most commonly it is a mixture of:

weak base and its salt with a strong acid,

weak acid and its salt with a strong base,

two acid salts.

Taking into account the fact that the role of pH buffers is to maintain a constant reaction of solutions, they are widely used in laboratory work. They are used, among other things, in the production of synthetic drugs and controlling their reaction, but not only. Some are involved in the creation of dyes or polygraphs and others are used to control the pH of finished foods and cosmetics. Buffering substances are also used in fermentation processes.

How do pH buffer solutions work?

During the conduct of many tests, the analysis of a particular substance is carried out and sometimes the need for an additional preparation arises. This can result in pH fluctuations. The role of buffering substances is to effectively prevent this from occurring and seek to maintain a constant pH of the preparation.

Among the most popular pH buffers are buffer solutions:

bicarbonate,

acetate,

ammonium,

phosphate,

borate.

The precision buffer solutions we offer in our EPRO online shop meet the strict requirements for their composition. This makes it possible to maintain an adequate level of safety and the highest substance quality. This is also important for maintaining the properties and effectiveness of the buffer.

How to use buffering agents correctly?

Before applying the buffer solution, the parameters of the ingredients (quantity and concentration) must first be calculated – this is determined by the required target volume and application. The ingredients should then be weighed, dissolved and the pH adjusted. The next step will be to make up the solution to the required target volume, describe it and document the actions. The product thus prepared can be stored for future use or used immediately.
