CEC of montmorilonite is

Solution (By Examveda Team)

Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals known as clay.
CEC is the cation exchange capacity of any material. A higher CEC value usually indicates more clay and organic matter is present in the soil, high CEC soils generally have greater water holding capacity than low soils.
CEC of montmorillonite is 60 - 100 Cmol_c (P⁺)/kg.
