When dilute aqueous solution of `AgNO_3` (excess) is added to KI solution, positively charged sol of Agl in formed due to adsorption of

When dilute aqueous solution of AgNO_3 (excess) is added to Kl solution, positively charged sol particles of Agl are formed due to adsorption of

Which to Kl soultion , positively charged sol particles of Agl are formed due to adsorption of ion

Addition of an excess solution of AgNO_(3) , to a solution of KI gives a positively charged Agl sol, while addition of an excess solution of KI to a solution of AgNO_(3) , results is a negatively charged Agl sol. Explain with reasons.

On adding AgNO_(3) solution into KI solution, a negatively charged coll oidal sol is obtained when they are in :
