state four characteristics of colloidal
Answers
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 a homogenous solution. This is because the suspended particles are so tiny that they are not conceivable by the naked eye.
