Which of the following characteristics of a colloid ____
A
It form two layers with a solution
B
It form turbid layer
C
It form heterogeneous layer
D
It form homogeneous layer
Explanation: 

Detailed explanation-1: -Which of the following is a characteristic of a colloid? Explanation: Since a colloidal particle does not from a single layer with solvents, the only possibility is to form a turbid layer where the solution is an intermediate between a miscible and immiscible solution.

Detailed explanation-2: -Colloids are very low diameter particles which are responsible for the turbidity or the color of surface water. Because of their very low sedimentation speed the best way to eliminate them is the coagulation-flocculation processes.

Detailed explanation-3: -Size of particles (colloids have particles of intermediate sizes) How a light beam shines through with the beam visible. How particles don’t settle or filter out. Separating particles requires special methods such as centrifugation. It is a heterogeneous mixture. More items •04-Jan-2022
