Question

speeding up sedimentation by making suspended particle heavier for 6th

Answer 1

Answer:

Loading process (in chemistry) is the process used to speed up the sedimentation process with the help of chemical called 'Alum'. Sedimentation involves settling down of suspended heavy particles present in a mixture at the bottom of the container when left undisturbed for some time.

The particles settled down are called sediment. After sedimentation, decantation is carried out by pouring off the liquid to separate the solid sediment.

The process of sedimentation is time consuming as the suspended particles take time to settle down to bottom. The process is sped up by the process called ‘loading’. It involves making the light suspended particles heavy. The chemical used for loading suspended particles is Alum. Alum’s fine particles load themselves on the suspended particles to speed up the sedimentation
