In which type of sedimentation, flocculent suspension of intermediate ...
Explanation:
Sedimentation is the process of settling of particles in a liquid under the influence of gravity. The rate of settling of particles depends on various factors such as particle size, shape, density, and concentration of particles in the liquid.
There are four types of sedimentation based on the concentration of particles in the liquid:
a)Type I sedimentation: In this type of sedimentation, dilute suspension of particles takes place. The concentration of particles in the liquid is very low, and individual particles settle down without any interaction with other particles.
b)Type II sedimentation: In this type of sedimentation, the concentration of particles in the liquid is higher than the Type I sedimentation. The particles settle down slowly, and there is an interaction between the particles due to their close proximity.
c)Type III sedimentation: In this type of sedimentation, the concentration of particles in the liquid is intermediate, and the suspension is flocculent. The particles settle down faster due to the formation of flocs, which are aggregates of particles held together by weak physical forces.
d)Type IV sedimentation: In this type of sedimentation, the concentration of particles in the liquid is very high, and the suspension is highly flocculent. The particles settle down rapidly due to the formation of large, dense flocs.
Therefore, the correct answer is option 'C', Type III sedimentation, where flocculent suspension of intermediate concentration takes place.
