- examples of suspension

and a fun quiz at the end

1. Suspension Mixture

2. What is a suspension mixture? A state in which particles of a substance are mixed with a liquid but are not dissolved in the liquid and can be separated by sieving . Solids do not dissolve in liquids like salt and water mixtures. Unstable . Particles in suspension settle out after some time. Particles are easy to see.

3. What is a suspension mixture? Suspensions are heterogeneous mixtures and some of the particles settle out of the mixture on standing. Since particles in suspension are much larger than those in solution, gravity pulls them away from the dispersion medium (water).

4. SUSPENSION Mixtures EXAMPLES

5. Muddy water Muddy water is a mixture of dirt and water. Muddy water is a typical suspension of relatively large solid particles suspended in water. If left alone, the solids will begin to settle to the bottom of the container.

6. Flour in water If you put flour in water, it becomes cloudy and you cannot see inside. This mixture is a suspension. Instead of dissolving, these large particles cloud the liquid.

7. Sand in water Instead of dissolving in water, sand floats and eventually sinks to the bottom. This interaction of sand and water perfectly explains what a suspension is.

8. SUSPENSION MIXTURE VS Solution Mixture Suspension Solution Heterogeneous Homogeneous Particle size: over 1000nm Pa rticle size: 0.01-1nm Particles settle out Particles Do not separate on standing Can be separated by filtration Cannot be separated by filtration

9. ReView ! True or False: in your answer sheet, Write “T” if the statement is True and “F” if not. Particles in Suspension is Easy to see. Muddy water is NOT an example of Suspension. Sand in Water is a perfect example of Suspension Suspension Mixture is a example of a homogeneous mixture. Heterogeneous mixture is when A mixture shows dissolving.

10. What I learned! Suspension or not? If the mixture is a suspension, write “S” and “NS” if not Muddy Water Fog Sugar in Water Sand in Water Coffee
