∙ 10y agoThe methods and principals used in the purification of colloids are:
Dialysis - This process is based on the fact that membranes contain very small pores through which only dissolved molecules and ions of the true solution can pass readily.
- Electro-dialysis - Used when the substance being removed is an electrolyte, substance is removed under an electronic field. The electrolyte icons pass through the membrance due to electrostatic pull of oppositely charged electrodes.
- Hemi dialysis - Blood of patients with kidney problems is purified by machines.
Ultra filtration - Filtration through filter paper treated with Gelatin or collodoin which allows only crystalloid particles can pass.
Centrifugation - Impurities are removed from colloids with the help of a machine of high speed called centrifugal machine. Colloids settle down while impurities remain in centrifuge.

Are colloids heterogeneous or homogeneous?
Colloids are stuck between heterogeneous and homogeneous mixture. So you can't say that it is a heterogeneous or homogeneous. It is both.
What are the physiological importance of protective colloids?
protective colloids are absorbed by solid particles,increase the strength of the double layer through hydrogen bonding and reduce the molecular interaction and aid in dispersion.they donot reduce the interfacial tension or the surface tension.
What are the examples of negatively charged colloids?
A colloid refers to a homogeneous mixture containing insoluble particles that do not settle out. Some examples of negatively charged colloids are silica, clay minerals and soil colloids.

What are three important products that are colloids?
Milk, butter, gelatin, and jelly are some examples of colloids. Aerosols can be categorised under colloids too.
Are colloids homogenous?
Colloids are very small particles of a substance suspended in a mixture making them homogeneous.

What are the negative effects of colloids on the environment?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
What are the harmful and beneficial effects of colloids and solutions?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
What is the visibility of colloids?
colloids are not visible due to their tiny particle size, (when the colloid is stable).

no
