Chemistry Question on Colloids
The basic principle of Cottnell's precipitator is
A
Le-chatelier's principle
B
peptisation
C
neutralisation of charge on colloidal particles
D
scattering of light
Answer
neutralisation of charge on colloidal particles
Explanation
Solution
In Cottnell?s precipitator, the charged particles are attracted towards the walls of precipitator, here they lose their charge and coagulate. Hence, the basic principle of Cottnell?s precipitator is the neutralisation of charge on colloidal particles.
