Buffers are substances that help reduce the changes in concentrations of ions which are known as hydrogen ions and hydroxide ions. The composition of a buffer in an acidic aqueous solution is combined containing a weak acid and salt of conjugate base of the weak acid. (Importance of Buffers, 2013) The composition of a buffer in a basic aqueous solution is combined containing a weak base and a salt of conjugate acid of weak base. A buffer solution resists the changes in pH therefore resisting modifications in hydronium ions and hydroxide ion concentrations. This is beneficial in chemical analyses, syntheses and standardization of pH. (Importance of Buffers, 2013)

The bicarbonate buffering system is known as an acid-base homeostatic mechanism involving the balance of chemicals: carbonic acid (H2CO3), bicarbonate ion (HCO3-), and carbon dioxide (CO2). Its major role is to maintain the pH in our blood and duodenum along with other important tissues found in our bodies. Carbonic acid is a weak acid therefore in equal balance with bicarbonate in solution. This buffer system is written as: H2CO3 + H2O H3O+ + HCO3- This buffer is known as a homeostatic system that can easily recognize and detect change, thus restoring equilibrium. This buffer only works if respiratory system is functioning properly. (Burgess, …show more content…
The phosphate buffer system consists of two ions: dihydrogen phosphate ions and hydrogen phosphate ions. When number of hydrogen ions in the bloodstream increases, the hydrogen phosphate ions accepts hydrogen ions to remain the equilibrium between the concentrations of both ions. The pH decreases. When the number of hydrogen ions in the bloodstream decreases, the dihydrogen phosphate ions release hydrogen ions. In order to increase the number of ions in the blood. The pH increases. This plays an important role with our tubules of kidneys. (Burgess, 2015) This buffer system functions in the internal fluid of all cells within our body and in other living organisms. The last factor that is beneficial to our survival is the protein buffer system. The protein buffer contains both basic and acidic solutions. This buffer is capable to ionise in two different methods, contingent on the pH of its surroundings. It contains an amino acid group and carboxyl group. The acid requires -NH2 which acts as a hydrogen acceptor which then becomes -NH. The alkaline requires –COOH which acts as a hydrogen donor which then becomes COO-. (Burgess,
