Question

Name the two properties that make solutions different from colloid.

​

Answer 1

Answer:

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.

I hope it help you....

Answer 2

Tyndall effect or Brownian movement and Particles of colloidal solution are the two properties that make solutions different from colloid.

Explanation:

Tyndall effect:

• The Tyndall effect, also known as the Tyndall phenomenon, is the scattering of a light beam by a medium containing microscopic suspended particles for example, smoke or dust in a room making a light beam entering a window visible.
• The effect is named after John Tyndall, a 19th-century British scientist who pioneered research into it.

Particles of colloidal solution:

• Small solid particles suspended in a fluid phase are known as colloidal particles.
• Their size ranges from 10 nanometers to many microns. This reduces the size of the particles to the point where they can be suspended in the fluid by thermal motion, as long as the buoyancy mismatch between the particles and the fluid is not too great.
