Buffers are common (and extremely important) in biological systems, including in human body. One of the most important biological buffers in human blood is the buffer established between carbonic acid and bicarbonate ion (H2CO3/HCO3–). At 25 oC, H2CO3 has a Ka1 of 4.45x10–7 and a Ka2 of 4.69x10–11. a. Will Ka1 or Ka2 of H2CO3 be instrumental in determining blood pH? Briefly explain your reasoning. b. Let’s pretend that there was an equal ratio of carbonic acid to bicarbonate (note...
