definition of colloids and it's classification

Answers

Answered by Suhaniv

Colloids:
Particle size: btw. 1-100 no
Appearance: foggy and translucent
Homogeneity: appears to be homogeneous but is heterogeneous
Tyndall effect: is observed
Can be separated by: centrifugation or ultra-centrifugation
Example: milk+ water

Suhaniv: Ohk

keerthanpro: can you give some examples please

keerthanpro: man are you here

Suhaniv: Smoke, clouds and fog and u can write the one I wrote above

Suhaniv: im a girl not man

dishapanda: Finely divided particles of any substance with diameter lying within 1 - 1000 nm range dispersed in any medium constitute colloidal system

keerthanpro: ok can you give examples of emulsions

keerthanpro: liquid in liquid colloids

Suhaniv: Ok wait

Suhaniv: I'm not sure for liquid in liquid but I know solid in liquid sol.

What are colloids or colloidal solutions?

A colloidal solution or a colloid is a uniform solution of two or more substances. The particles are relatively very small that the solution appears as a homogeneous mixture but it is not.

Properties of colloids:

 Colloids are heterogeneous in nature.

 The particles of a colloid cannot be seen through naked eyes.

 The particles scatter a beam of light passed through a colloid and produce Tyndall effect.

 Colloids are stable in nature. The particles of colloids do not settle down if left uninterrupted.

 We cannot separate the particles of a colloid through filtration. We use a method called Centrifugation to separate the particles of a colloid.

Classification of Colloids

Dispersed Phase – The dispersed particles or the solute-like components in a colloid

Dispersing Medium – The substance in which these solute-like particles are added.
