a colloid ?​

Answer 1

Answer:

A colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye.

Properties :

• They are heterogenous mixtures.
• The size of particles of colloids is too small to be seen by naked eye.
• They scatter light passing through them making its path visible.

Answer 2

Answer:

colloid is a heterogeneous mixture. 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.
