Problem

The pH of blood stream is maintained by a proper balance of

\text{H}_2\text{CO}_3

and

\text{NaHCO}_3

concentrations. What volume of 5 M

\text{NaHCO}_3

solution should be mixed with a 10 mL sample of blood which is 2 M in

\text{H}_2\text{CO}_3

in order to maintain a pH of 7.4?

K_a

for

\text{H}_2\text{CO}_3

in blood is

7.8 \times 10^{-7}
