Question

To prepare a suspension of soil chalk powder and fine sand in water

Answer 1

A suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, and will eventually settle or sediment and is called sedimentation.

Soil, chalk and fine sand is taken in a beaker full of water, Now the 3 layers are formed according to their particle size.

Chalk then fine sand and then soil. These is the layer formed.

Answer 2

Suspension of soil chalk powder

Explanation:

• Take three perfect and dry containers. Put 100 ml of water to them and afterward 10 g of all these ( soil, chalk powder, fine sand) in various measuring glasses. Mix them with glass bar and permit them to represent at some point and note the perception.  
• In the event that it were an answer, it would be a homogeneous blend.
• A homogeneous blend would be absolutely straightforward and the way of a limited light emission coordinated through the blend would not 'appear' by any stretch of the imagination.  
• Chalk being CaCO₃ doesn't break down in water, it shapes a 'strong in fluid' scattering.  
• Regardless of whether the measure of scattered solids is little to such an extent that with the unaided eye, the test with the limited light bar will on the double uncover that the blend is in homogeneous.
