Answer» neutralisation of charge on colloidal particles scattering of light Le chatelier 's principle peptisation Solution :In Cottrell smoke precipitator , the smoke is allowed to pass through a chamber having a series of PLATES charged to very high POTENTIAL (20000 to 70000V). Charged particles of smoke GET attracted and by charged plates and the gases coming out of CHIMNEY preciptated become free of charged particles.
