a. One of the buffers in blood plasma is a mixture of dihydrogenphosphate ions (H 2 PO

Question:

a. One of the buffers in blood plasma is a mixture of dihydrogenphosphate ions (H₂PO₄^–) and hydrogenphosphate (HPO₄^2–) ions.

i. Identify the conjugate acid and base in this buffer.

ii. Write a balanced equation for the equilibrium between these two ions.

b. Some proteins in the blood can act as buffers. The equation below shows a simplified equilibrium equation for this reaction. (Pr = protein) HPr ⇌ H⁺ + Pr ^–

Explain how this system can act as a buffer to prevent the blood getting too acidic.
