Not in NEET syllabus

According to the carbonic acid exchange theory of mineral salt absorption by roots, which of the following is incorrect?

(A)CO2 released by root respiration combines with soil H2O to form H2CO3.
(B)H2CO3 dissociates into H+ and HCO3⁻ ions in the soil solution.
(C)Cations thus released into the soil solution are adsorbed on clay particles.
(D)H+ ions may be exchanged for cations adsorbed on root cells in exchange for anions (e.g. Cl⁻ ions).Correct

Answer: (D)

Solution

In the carbonic acid exchange theory, CO2 from root respiration forms H2CO3 with soil water, which dissociates into H+ and HCO3⁻; the H+ ions displace cations adsorbed on
