Question

please write the properties of collodial solution ​

Answer 1

Properties of colloidal solution---

1.The particles are more than 1 nm but less than 100 nm.

2.It scatters a beam of light passing through it.

3 . They are quite stable.

4.It can be separated by the process of centrifugation.

5.The particles of colloidal solution are too small to be visible by naked eyes.

Answer 2

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 a homogenous solution. This is because the suspended particles are so tiny that they are not conceivable by the naked eye.
