Question

What are the two properties of colloidal substance?

Answer 1

Answer:Properties of Colloidal Solutions

A colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Owing to this peculiar structure of colloid, it has varied physical and chemical properties. Let us explore more about the physical, chemical, optical as well as electrical properties of colloidal solutions.

Answer 2

Answer:

A colloid ( or colloidal solution) appears to be homogenous but actually it is heterogeneous.

• The size of particles in colloidal solution is intermediate to that of solution particles and suspension particles (i.e the particle size is in between 1nm - 100nm.)

• The particles of colloidal solution are unstable.

• The particles of colloid can pass through a filter paper. They can only get separated by the process of centrifugation.
