Question

write the properties of colloid
​

Answer 1

colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye. When a beam of light is passed through a colloid then the path of the light becomes visible. For example milk, smoke etc..

Answer 2

Answer:

Stability: Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution.

Filterability: Colloids require specialized filters known as ultrafilters for filtration. They readily pass through ordinary filter papers without yielding any residue.

Heterogenous nature: Since colloids consist of two phases, the dispersed phase as well as the dispersion medium, they are known as heterogeneous in nature.

Homogenous appearance: Even though colloids have suspended particles and are heterogeneous in nature, they appear as if it is a homogenous solution. This is because the suspended particles are so tiny that they are not visible by the naked eye.
