When dilute aqueous solution of AgNO₃ (excess) is added to KI solution, positively charged sol parti — Surface Chemistry Chemistry Question
Question
When dilute aqueous solution of AgNO₃ (excess) is added to KI solution, positively charged sol particles of AgI are formed due to adsorption of ion
Answer: B
💡 Solution & Explanation
Since AgNO₃ is in excess, the common Ag⁺ ions are preferentially adsorbed on the AgI surface, forming a positively charged sol. Therefore, correct answer is B.
