Answer 2

Hey dear,

● Answer -
When NaCl solution is added to a Fe(OH)3 colloidal solution, coagulation takes place.

● Explanation -
- When salt is added to water, it dissociates into Na+ & Cl- ions.
NaCl + aq ---> Na+ + Cl-
- As particles of Fe(OH)3 solution are positively charged, they get coagulated in presence of negatively charged Cl- ions.

Hope this helps you...
