The basic principle of Cottnell's precipitator is
Options
- ALe-Chatelier's principle
- Bpeptisation
- Cneutralisation of charge on colloidal particles
- Dscattering of light
Correct answer
C. neutralisation of charge on colloidal particles
Step-by-step solution
The basic principle of Cottnell's precipitator is neutralisation of charge on colloidal particle by attracting them towards the wall of oppositively charged precipitator. Thus, lose their charge and coagulate colloidal particle.
