In the bohr effect is it true that when h+ are high that is when co2 is high which means low ph(3-5)?

Question

please explain any help will be appreciated

Answer 1

Yes, for pH in the range of 3 to 5, H+ is high relative to OH- and all of the HCO3- is protonated to H2CO3 and therefore dehydrated to CO2(aq).  The reason why is that this equilibrium:

H2CO3  <=> H+   +   HCO3-

shifts to the left as H+ increases.
