Why a negatively charged sol is obtained on adding AgN`O_(3)` solution to KI solution?

A reddish brown positively charged sol is obtained by adding small quantity of FeCl_(3) solution to freshly prepared and well washed Fe(OH)_(3) precipitate. How does it take place ?

When FeC_3 solution is added to NaOH a negatively charged sol is obtained. It is due to the:

When FeCl_3 solution is added to NaOH a negatively charged sol is obtained. It is due to the:

A negatively charged sol can be formed by peptizing a solution of
