Buffer In The Blood (d) blood contains a mixture of carbonic acid, h2co3, and hydrogencarbonate ions, hco–. 3 explain how the carbonic acid–hydrogencarbonate mixture acts as abuffer. in your answer include the equation for the equilibrium in this buffer solution and explain how this equilibrium system is able to control bloodph.[5] [total:22marks] [4]. (ii) healthy blood at a ph of 7.40 has a hydrogencarbonate : carbonic acid ratio of 10.5 : 1. a patient is admitted to hospital. the patient’s blood ph is measured as 7.20. calculate the hydrogencarbonate : carbonic acid ratio in the patient’sblood.

(ii) write the expression for the acid dissociation constant of butanoic acid. Carbonic acid, h,co;, is a weak bronsted lowry acid formed when carbon dioxide dissolves in water. healthy blood is buffered to a ph of 7.40. the most important buffer solution in blood is a mixture of carbonic acid and hydrogencarbonate ions, hco; (a) explain how the carbonic acid hydrogencarbonate mixture acts as a buffer in the control of blood ph.

Outlining how blood is able to buffer ph by using carbonic acid and hydrogen carbonate ions dissolved in blood plasma. the effect on position of equilibrium. The levels of carbonic acid (h 2 co 3) in the blood are primarily controlled by respiration. when the body produces excess carbon dioxide (co 2), it reacts with water to form carbonic acid: co 2(aq) h 2 o (l) ⇌ h 2 co 3(aq) to reduce the concentration of carbonic acid, the body can exhale co 2 through the lungs.
