Some soil colloids exhibit positive charges under highly acid conditions.To what are these charges likely due? A)protonation of some hydroxy groups by excess H⁺ ions B)the adsorption of Al³⁺ ions on the colloid C)the release of some OH^- ions leaving an unsatisfied positive charge on the colloid D)substitution of lower valent atoms for higher valent atoms in the octahedral sheet E)increase in the level of H⁺ ions on the exchange complex

Question

Quizplus · Accepted Answer

Under highly acidic conditions, excess H⁺ ions can protonate hydroxy groups on soil colloids, leading to positive charges.
