The following reactions are known to occur in the body

CO₂ + H₂O H₂CO₃

H₂CO₃ H⁺ + HCO_3–

If CO₂ escapes from the system

(A) pH will decreases

(B) Hydrogen ion concentration will diminish

(C) H₂CO₃ concentration will remain unchanged

(D) The forward reaction will be favoured

Best Answer

(B)

CO₂ + H₂CO₃ H⁺ + HCO₃^-

If CO₂ escapes concentration of H₂CO₃ will decrease

hence equilibrium shifted in backward direction

So [H⁺] ion will diminish
