Fast answer​

Answer 1

$\huge\star\underline\mathtt{Answer:-}$

Properties of colloids:-

$\longrightarrow$A colloid appears to be homogenous but actually it is heterogeneous.

$\longrightarrow$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.

$\longrightarrow$The particles of most of the colloids cannot be seen even with a microscope.

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

$\longrightarrow$The colloids are quite stable.

$\longrightarrow$A colloid scatters a beam of light passing though it.

Answer 2

Answer:

Properties of a colloid

The size of particles of a colloid is too small to be individually seen by naked eyes. Colloids are big enough to scatter a beam of light passing through it and make its path visible. They do not settle down when left undisturbed, that is, a colloid is quite stable.

hope help u mate ✌
