Question

differentiate between colloid solution and suspension​

Answer 1

Surface Chemistry

Answer :

★ A colloid is a heterogeneous system in which one substance (dispersed phase) is dispersed as very fine particles in another substance called dispersion medium. The range of diameters of colloidal particles is between 1 and 1000nm$.$

Depending on size of particles, solution are divided into three classes :

⧪ True solution : In true solution size of particles is less than 1nm.

⧪ Suspension : In suspension size of particles is greater than 1000nm.

⧪ Colloidal solution : In colloidal solution size of particles lies from 1nm to 1000nm.
