Read the Assertion and Reason below and choose the correct option. — Surface Chemistry Chemistry Question

💡 Solution & Explanation

As₂S₃ is a negatively charged colloidal sol. The highly charged Fe³⁺ cation is very effective in neutralizing this negative charge and causing physical coagulation (precipitation). However, it does not undergo a bulk chemical reaction to form Fe₂S₃ in this process. Thus, the assertion is true, but the reason is false. Therefore, correct answer is C.
