Question

K fixing power of clay minerals follows the order:
(A) Illite
(B) Montmorillonite
(C) Kaolinite
(D) Vermiculite

• A. (A), (B), (C), (D)
• B. (D), (A), (B), (C)
• C. (B), (A), (D), (C)
• D. (C), (B), (D), (A)

Hint:

K fixation depends on the layer charge and interlayer spaces in clay minerals.
