RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate
