five examples of suspension and colloids with their physical properties
Answers
Answer:The five examples of suspension are as follows:
Mixture of chalk and water
Muddy water
Mixture of flour and water
Mixture of dust particles and air
Fog
Milk of magnesia, etc.
physical properties are as follows:
Suspensions are a heterogeneous mixture of two or more substances.
Particles of the solute do not dissolve in the solvent rather they remain suspended in bulk throughout.
The size of particles of suspension is large enough to be visible from naked eyes. They are greater than 1 nanometer (?10?^(-9) meter).
It shows Tyndall effect because of their large size of particles.
When it is left for some time, particles get settled in the bottom. Therefore, it is not stable.
The particles in it can be separated through the process of filtration.
It does not scatter light when particles are settled because in this case suspension breaks.
:The five examples of colloids are as follows:
Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium. ... A liquid dispersed in a gas is referred to as a fog.
physical properties are as follows:
Properties of a colloid
• A colloid is a heterogeneous mixture.
• The size of particles of a colloid is too small to be individually seen by naked eyes.
• Colloids are big enough to scatter a beam of light passing through it and make its path visible.
• They do not settle down when left undisturbed, that is, a colloid is quite stable.
• They cannot be separated from the mixture by the process of filtration. But, a special technique of separation known as centrifugation can be used to separate the colloidal particles.
