Iron metal can reduce silver ions - CHEMISTRY COMMUNITY

Oct 03, 2011  Ag is being reduced (gaining electrons) and iron is being (oxidized) giving off electrons. Because Fe is being oxidized, it is giving its electrons away, and those electrons go to , thus reducing into Ag(s). Because of that, we say iron metal can reduce silver ions.

Jul 24, 2016  "0.0220 moles" You're dealing with a redox reaction in which iron, "Fe", reduces the silver cations, "Ag"^(+), to silver metal, "Ag", while being oxidized to iron(II) cations, "Fe"^(2+). The net ionic equation that describes this reaction looks like this "Fe"_ ((s)) + 2"Ag"_ ((aq))^(+) -> "Fe"_ ((aq))^(2+) + color(red)(2)"Ag"_ ((s)) darr The silver metal produced by the reaction will be ...
