A chemical buffer is a substance that helps maintain a stable pH by either reacting with excess acids or bases to minimize a change in pH, or by releasing or absorbing hydrogen ions to resist changes in pH. Common examples include bicarbonate ions in blood and acetic acid in vinegar.
Buffers maintain the body at a set point. An example is the acid base buffer in your blood. Carbonate (CO3) helps keep the blood pH between 7.35 and 7.45. This works by absorbing hydrogen ions when the pH drops to 7.35 and releasing hydrogen ions when the pH rises to 7.45 (this is a simplified explanation since the chemistry is slightly more fluid and a bit more complex).
A physiological buffer is a system that stabilizes pH by controlling the body's output of acids, bases, and carbon dioxide (mostly the respiratory and urinary system). These are not part of buffer "systems". A chemical buffer either binds or releases hydrogen ions to stabilize (raise or lower) pH. Cemical buffers act as mixtures called buffer systems.
Buffers are a medium in which life happens. chemically they are the environment that will keep the pH of the surrounding stable with no drastic change. Enzymes, cells and other biomolecules are sensitive to pH change, hence a buffer system is needed to maintain the pH.

What is the substance that neutralizes small amounts of acid or bases added to a solution?
Acids are added to neutralize base and inverse; a buffer only stabilizes the pH.
What is a buffer reaction?
A buffer reaction is a chemical reaction involving a buffer solution, which resists changes in pH when an acid or base is added. Buffer solutions contain a weak acid and its conjugate base, or a weak base and its conjugate acid, to help maintain the pH of the solution within a specific range.
What is a chemical compound that helps control the pH of a solution by adding or removing hydrogen ions is a(n)?
Buffer
What is chemical equation when a strong acid is added to a buffer solution containing NaF and HF?
When a strong acid is added to a buffer solution containing NaF and HF, the strong acid will react with the weak base (F-) to form HF. The buffer solution will resist changes in pH by the common ion effect, maintaining the solution's acidity around the initial pH of the buffer. The chemical equation can be written as H+ + F- ↔ HF.
Why is the bicarbonate buffer sytem considered a open buffer system?
The bicarbonate buffer system is considered an open buffer system because it can interact with other chemical species in the body to help maintain a stable pH. It involves the reversible conversion of carbonic acid to bicarbonate ion, allowing it to adapt to changes in pH by either accepting or releasing protons. This flexibility enables it to effectively buffer against fluctuations in acidity.
What is the chemical of an extraction buffer?
ethyl or grain
Is a chemical or combination of chemicals that keeps pH within normal range?
A buffer is a chemical or a combination of chemicals that helps maintain a stable pH within a specific range by resisting changes in pH when an acid or a base is added to the solution. Buffers are crucial for maintaining the correct environment for many biological processes to occur.
What is the chemical substance that resists change in pH?
A buffer solution is a chemical substance that resists changes in pH when small amounts of acid or base are added. Buffers are made up of a weak acid and its conjugate base, or a weak base and its conjugate acid, which work together to maintain the pH of a solution.
What is a chemical bond that helps control the pH of a solution?
I suppose that you think to a buffer, not bond.
The name given to a chemical system that prevent changes in hydrogen ion concentration?
A buffer
What is the substance that neutralizes small amounts of acid or bases added to a solution?
Acids are added to neutralize base and inverse; a buffer only stabilizes the pH.
What are the applications of buffer solution?
Buffer solutions are commonly used in biochemical and chemical processes where it is important to maintain a stable pH, such as in biological research, pharmaceuticals, and food chemistry. They are also used in analytical chemistry for calibration and in chemical synthesis to control the pH of reactions. Additionally, buffer solutions are used in medical applications, such as in blood testing and diagnostic assays.

What is swimming pool buffer?
Swimming pool buffer is a type of chemical treatment used to adjust the pH balance of the water. It helps to maintain proper water conditions which are ideal for swimming.
A solution that is resistant to change in pH?
A buffer solution is resistant to changes in pH because it contains a weak acid and its conjugate base, which can react with added acid or base to maintain a relatively constant pH. Buffers are commonly used in biochemical and chemical systems to prevent drastic changes in pH levels.
What is a chemical compound that helps control the pH of a solution by adding or removing hydrogen ions is a(n)?
Buffer
Is Hexamine a Buffer?
No, hexamine is not a buffer. It is a heterocyclic organic compound that can be used as a precursor for the synthesis of other chemical compounds. Buffers are solutions that resist changes in pH when an acid or base is added.
