Question

properties of a colloid

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

Answer 2

Size of solute particles bigger than true but smaller than suspension.

Solute particles can't be seen with naked eye.

Seems homogeneous but actually heterogeneous mixture.

Particles can't be separated by filtration.

Translucent

Stable solutions.

Show tyndall effect..

Colloid particles pass through filter paper but not through parchment paper.

e.g,, Milk ,, blood....
