a solution of ethanoic acid and sodium ethanoate ....
One example is the blood. It's buffered mainly by H2CO3 (carbonic acid) and HCO3- (bicarbonate), both of which are produced through metabolic RXNs and ion exchanges from cells in the kidney tubules, even by the red blood cells themselves. Such buffering by bicarbonate allows our blood to stay within normal pH limits (around 7) when we are either breathing in a lot of oxygen or breathing too little oxygen. Metabolic actions are linked with exercise or exertion are an example where the body produces a lot of acidity which needs to be neutralized by a buffer. Excess hydrogen ions (or the equivalent thereof) in the muscle tissue cause shape changes in our Hemoglobin (the body's molecule that transports oxygen from lungs to tissues) which then make oxygen leave that hemoglobin in the specific tissues that need it (the oxygen) the most. In that way, even hemoglobin can be considered a buffer.

∙ 12y ago1)H2CO3/HC03- the carbonic acid/bicarbonate buffer system
H2CO3<--->HCO3- + H+
or expressed in a more important form, as in our bodies where our renal and respiratory systems can further regulate our pH balance
C02 + H20 <----> H2CO3- <----> H+ + HCO3-
(Lung Side, for explanation purposes)(Kidney Side, for explanation purposes)
Using Le Chatelier's principle, which states that if you put a stress on a system at equilibrium the system will act in a way to relieve that stress:
your respiratory rate can increase or decrease the output of CO2, in effect, adding more CO2 will push this system to the right, increasing H+ concentration and therefore lowering your pH level. (The lower the pH the higher the H+ concentration)
your renal system can either retain/excrete H+ or HCO3- according to the stresses placed on your system.
2)H2PO4-/HPO42- phosphate buffer system
H2PO4- (aq) + H20 (l) <-----> H30+(aq) + HPO42-(aq)
(acid) (base) (conjugate acid) (conjugate base)
3)Proteins Buffers (Proteins have amino acid side chains allowing them to work as weak acids and weak bases, pH imbalances in our bodies can warp these proteins (Change their tertiary structures) so they may no longer be able to function correctly. )
---before edit----
1)heamoglobin buffer (/edit/ this is a protein)
2)bicarbonate buffer
3)amino buffer (/edit/ this represents the amino acid side chains on proteins)

What is the definition of a buffer in chemistry?
As a noun, "buffer" in chemistry means a mixture of at least two materials that resists changes in pH value when small amounts of acid or base are added to the mixture. As a verb, "buffer" in chemistry means to add at least one substance to a substance or mixture that is not originally a buffer that will cause the mixture formed by the addition to become a buffer in the noun sense.
What is a buffer in basic chemistry?
Buffers maintain a constant pH.
What is buffer capacity and what are the factors that effect the buffer capacity?
it is defined the capability of a buffer to resist the change of pH.it can be measured quantity that how much extra acid or base , the solution can absorb before the buffer is essentially destroyed. buffer capacity of a buffer solution is determined by the sizes of actual molarities . so , a chemist must decide before making the buffer solution.
What is called buffer zone?
It is, for example, a buffer zone between two hostile nations that serves to prevent conflict
What is the chemistry of common buffers used in microbiological media?
Some of the chemistry of common buffers used in microbiological media include amino acids and peptones. Usually, an acidic buffer is used.

How did binding buffer get its name?
A binding buffer is a substance used in chromatography to fix a specific compound.For example this buffer can be linked to a protein.
Weak acid or base that prevents sharp swings in pH?
A buffer is the substance that prevents rapid or large swings in pH. There are two types of buffers; acidic buffers and basic buffers.

A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.

Why buffer used in mobile phase?
buffers in terms of chemistry is that which resists the pH of solution.and maintain H+ ion conc
Significance of chemistry in your daily lives?
Chemistry plays a huge role in your daily life. Boiling water to make food for example is an example of chemistry.
