When too much protons are added to the blood, the buffer system gets a little help from the lungs and the kidneys: The lungs remove excess #CO_2# from the blood #-># this increases the pH; The kidneys remove excess #HCO_3^(-)# from the body #-># this lowers the pH.

WebTherefore, a buffer resists changes in pH because it contains both an acid, HA, to neutralize added OH minus ions and a base, A minus, to neutralize added H plus ions. There are two ways to make a buffer solution. The first way to make a buffer solution starts with an aqueous solution of a weak acid, HA.
WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25.
