The pH of blood is maintained by the balance between `H_(2)CO_(2)` and `NaHCO_(2).` If the amount of 'CO_(2)', in blood is increased, how will it affect the pH of blood?

Options

A. pH will remain same
B. pH will be 7
C. pH will increase
D. pH will decrease

Answer

A

Explanation

`H_(2) + CO_(2) hArr H^(o+) + HCO_(3)^(ɵ)`. If `CO_(2)` is increased, according to Le Chatelier.s principle, `[H^(o+)]` will increase, thereby pH will decrease.
