a) what is a colloidal solution? b) write any two properties of a colloidal solution?
Answers
A 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.
Answer:
A colloid is a mixture that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container.
Explanation:
1) Colloidal solutions shows Tyndall effect or Brownian movement.
2) Particles of colloidal solution do not settle due to gravity but they may settle due to Centrifugation. Dispersed phase and Dispersion medium are the two components of colloidal solution
