Answer 2

Answer:

The suspension of soil chalk powder and fine sand in water laboratory  

It is the solution in which the solute size is more than 100 nm .

Properties of suspension

• It is a heterogeneous mixture.
• Particle size is more than 1000 nm (10-6 m) and can be seen with naked eyes.
• The particles of suspension, in its suspended form scatter a beam of light, i.e., shows Tyndall effect.
• It is unstable.
• The particles can be separated by filtration.
• It is opaque.

To prepare a suspension of soil, chalk powder and fine sand in water. Suspension of sand in water:

• Take say 100 mL of distilled water in a beaker
• To it add say, 10 g of fine sand in it.
• Set well using a glass rod.
• In few minutes you will see the suspension gets ready .
