Question

_____ is not type of co-precipitation.
(a) surface adsorption
(b) occlusion
(c) crystallization
(d) mechanical entrapment​

Answer 1

a) surface adsorption is the answer

Answer 2

c) crystallization is not type of co-precipitation.

• crystallization :- crystallization is a process in which the transformation of liquid or solution into a solid crystal form in which the atoms are arranged having very less interstitial space.

• surface adsorption :- surface adsorption is a surface phenomenon in which molecular atomic or ionic species get accumulated at the surface of another substance .

• occlusion :- Occlusion is a phenomenon in which absorption of gases takes place on the surface of metal .

• Mechanical entrapment :- Rapid growth of two crystals that lie close together traps a pocket of solution

So the correct answer is C) Crystallization
