Q590
The reason of soil flocculation is
A.
Lowering of Zeta potential
AnswerB.
Increase in Zeta potential
C.
No effect on Zeta potential
D.
None of the above
Answer: Option A
Solution
Answer: Option A
Solution:
Flocculation refers to a state when primary soil particles (sand, silt and clay) are drawn to each other by inter-particle forces to create microscopic floccules or clumps.The reason for soil flocculation is the Lowering of Zeta potential. Zeta potential is a property of charged interfaces within the soil solution. Thus, when it is lowered, the soil particles clump and floccules are formed.
