Question

A biochemist is studying a buffer system in blood with a pKa of 6.1. If the pH of the blood is 7.4, what is the ratio of bicarbonate (HCO3-) to carbonic acid (H2CO3)?

Accepted Answer

Ratio = 10^(7.4 - 6.1) = 19.95

Answer

Ratio = 10^(7.4 - 6.1) = 1.95

Answer

Ratio = 10^(7.4 - 6.1) = 0.95

Answer

Ratio = 10^(7.4 - 6.1) = 0.05
