Question

$Fe(OH{)}_3$ sol contains positively charged colloidal particles.

• A. True
• B. False

Answer 1

The correct option is A True

$Fe(OH{)}_3$ sol contains positively charged colloidal particles. So, the sol particles move to the negative electrode where their charge is neutralised and they aggregate and finally precipitate out. Thus, the entire colloidal matter settles down at the bottom.
