Following intense exercise, the blood pH was determined to be 7.1. If the HCO3- is 7.5mM and the pKa for HCO3- is 6.1, what is the CO2 concentration in the blood
Answers: 1
= ![[HCO_3^-]=7.5\ \text{mM}](/tpl/images/1043/5758/0c683.png)
for 
of blood = 7.1
![pH=pK_a+\log\dfrac{[HCO_3^-]}{[H_2CO_3]}\\\Rightarrow 7.1=6.1+\log \dfrac{7.5}{[H_2CO_3]}\\\Rightarrow 1=\log\dfrac{7.5}{[H_2CO_3]}\\\Rightarrow 10^1=\dfrac{7.5}{[H_2CO_3]}\\\Rightarrow [H_2CO_3]=\dfrac{7.5}{10}\\\Rightarrow [H_2CO_3]=0.75\ \text{mM}](/tpl/images/1043/5758/de1d0.png)
, ![[H_2CO_3]=[CO_2]](/tpl/images/1043/5758/917ed.png)
, ![[CO_2]=[H_2CO_3]=0.75\ \text{mM}](/tpl/images/1043/5758/a5e1f.png)
