Explanation:
Physical Properties of Colloidal Solutions
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.
Answer:
General properties of colloidal systems are as follows:
(1) Colloidal system is heterogeneous and consists of two phases, dispersed phase and dispersion medium.
(2) The dispersed phase particles pass slowly through parchment paper or animal membrane, but readily pass through ordinary filter paper.
(3) The colloidal systems exhibit optical property like Tyndal effect, kinetic property like Brownian motion, electrical properties like electrophoresis a colour.
