The sol given below with negatively charged colloidal particles is: 3 3 3 2 3 2 3 3 – (A) FeCl added — Surface Chemistry Chemistry Question
Question
The sol given below with negatively charged colloidal particles is: 3 3 3 2 3 2 3 3 – (A) FeCl added to hot water (B) KI added to AgNO solution (C) AgNO added to KI solution (D) Al O .xH O in water
Answer: C) AGNO ADDED TO KI SOLUTION
💡 Solution & Explanation
When AgNO is added to KI solution, all of AgNO is converted into AgI which is surrounded by remaining KI solution. The common ion, I gets adsorbed to AgI particles which makes the colloidal particles negatively charged.
