Agglomeration of individual particles into clusters (flocs) is called flocculation. To prevent flocculation, the most commonly used dispersing agents are________________?
Correct answer: C. Silicates & phosphates
- A. Carbonates
- B. Sulphates
- C. Silicates & phosphates
- D. Bi-carbonates
Explanation
Silicates and phosphates commonly act as dispersants by giving particles like charges and reducing their tendency to form flocs. Carbonates and bicarbonates are not the usual choices for preventing flocculation.
