Question

Assertion : Colloidal solutions show colligative properties. Reason : Colloidal particles are large in size.

Answer 1

Smoke is the colloidal solution of the solid particles such as carbon, arsenic, dust particles etc. ... This is done by the cottrell smoke precipitator which neutralizes the charge on the carbon particles and neutralizes them. In this way smoke coming out of the chimneys gets free from the charged particles .
