Molecular sieves are porous____________________?
Correct answer: C. Synthetic zeolites crystals/metal alumino-silicates
- A. Alumina
- B. Silica
- C. Synthetic zeolites crystals/metal alumino-silicates
- D. None of these
Explanation
Molecular sieves are crystalline synthetic zeolites made from metal aluminosilicates. Their uniformly sized pores selectively admit molecules according to size and shape.
