Describe the role of hemoglobin as a buffer
WebThe body's acid– base balance is tightly regulated to keep the arterial blood pH between 7.38 and 7.42. Buffer solutions keep the pH constant in a wide variety of chemical actions. A buffer solution is a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid. The bicarbonate buffering system maintains optimal pH ... WebWhile the third buffer is the most plentiful, the first is usually considered the most important since it is coupled to the respiratory system. Carbonic acid (H 2 CO 3) is a weak acid and is therefore in equilibrium with bicarbonate (HCO 3-) in solution. When significant amounts of both carbonic acid and bicarbonate are present, a buffer is formed.
