Question

Explain properties of colloids.
Fast answer​

Answer 1

$\huge\bigstar\underline\mathfrak{Answer:-}$

Properties of colloid are :-

• A colloid appears to be homogenous but actually it is heterogeneous.

• The size of particles in a colloid is bigger than those in a true solution but smaller than those in a suspension.It is between 1nm to 100nm in diameter.

• The particles of most of the colloids cannot be seen even with a microscope.

• The particles of a colloid can pass through a filter paper and hence cannot be separated by filteration.

• The colloids are quite stable.

• A colloid scatters a beam of light passing though it.

Answer 2

Physical Properties of Colloidal Solution

• 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.
