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, blood red solution and white precipitate. The balance chemical equation for the reactions were Fe2+ + K3Fe(CN)6 - Fe(CN)36 +K2 +Fe , Fe3+ + KCSN  Fe(SCN)3+K and Ag+ + HCI  AgCl + H+. The bonding between the ions in the solution is weak because it can be separated easily and they are very reactive to the
And when an acid was added chromate turned orange while dichromate remained orange. The acid solution used was H2SO4 because it is highly acidic. 2CrO4-2(aq) + 2H3O+(aq) ⇄ 3H2O(L) + Cr2O7-2(aq) is the balance chemical equation of the system. When the acid solution is added the equilibrium shifts to the left making the solution orange and when basic solution is added to the solution the equilibrium shifts to the right making the solution yellow. Therefore, chromate is the stable as base and dichromate is stable as
