The pH of the bloodstream is maintained by a proper balance of `H_2CO_3` and `NaHCO_3` concentrations. What volume of 5 M `NaHCO_3` solution should be mixed with a 10 mL sample of blood which is 2 M in `H_2CO_3` , in order to maintain a pH of 7.4? `K_ą` for `H_2CO_3`, in blood is `7.8xx 10^(-7)`

Explanation

mm of `NaHCO_3 = 5 xx x `
mm of `H_2CO_3 = 2 xx 10`
Apply henderson.s equation and calculate x.
78.36mL
