Question

List some properties of Collidal solutions .......

Answer 1

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.

Properties of Collidal Solutions ::-

□ Nature 》 Colidal Solution are heterogeneous in nature consisting of two phase called dispersed phase and dispersion phase.

♤ Size 》 Size of the particles lies in the range from 1 to 100 Nanometre.

♡ Filterity 》 Collidal Solutions can pass through ordinary filter paper but cannot pass through a semi-permeable membrane .

♢ Stability 》 Colloidal Solutions are quite stable and do not Settle Down When left undisturbed .

♧ Visibility 》 Colloidal particles are not visible to the naked eye but can be seen through Microscope.
