Question

Consider the following statements:
1. Mica is a clay mineral.
2. The shape of clay particle is usually flaky.
3. A particle of kaolinite is electrically charged.

Which of these statements is/are correct?

• A. 1, 2, and 3
• B. 1 and 3 only
• C. 2 and 3 only
• D. 2 only

Answer 1

The correct option is D 2 only

(d)
Clay soils have flaky particles to which water adheres, thus imparting the property of plasticity. Kaolinite. This clay mineral is the weathering product of feldspars. It has a white, powdery appearance. Because kaolinite is electrically balanced, its ability of adsorb ions is less than that of other clay minerals.
