Question

Laxmi says that sedimentation and decantation are used at home while cleaning rice and pulses for cooking. Describe the sediments in this process.

Answer 1

1. While cleaning rice we wash rice with water. Rice settles down in the water as sediments and the lighter impurities float. This is called sedimentation. 

2. The water gets separated from the sediment (rice). This process is called decantation. 

3. The same process takes place while washing pulses.
