The electronegative charge on 2:1 type silicate clays is due primarily to _____. A)ionization of surface OH groups B)substitution of one metallic atom for another in the crystal structure of the clay C)extremely small size of the individual colloid particles D)the effect of pH on the presence of H⁺ ions in the exchange complex E)the preponderance of tetrahedral sheets compared to octahedral sheets

Question

Quizplus · Accepted Answer

The electronegative charge on 2:1 type silicate clays primarily arises from the substitution of one metallic atom for another in the crystal structure of the clay, leading to a net negative charge that attracts cations.
