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

    Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value, which can be obtained using the formula: Kc = [product] [reactant] In this experiment, we used a spectrophometer to…

    CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant, a…

    Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward, at the same time by the same amount, is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second, Effect of Temperature on Equilibrium, the solution turned into a light brown gas when it was placed in the refrigerator…

    two types of chemical reaction that occur one goes only in one direction and the other one is reversible. A reversible reaction is when a products starts to form the backward reaction starts where the products turns back to reactant molecules. When the rate of forward and backward reaction is already equal and the concentrations of the reactants and products no longer change with time we can say that chemical equilibrium is already achieved. A reaction is said to be at equilibrium when the following…

    Discovering the equilibrium constant for a reaction is very helpful for understanding that reaction. Knowing the equilibrium constant of a reaction is important because it allows you to calculate how much product will ultimately be formed during a reaction. Moreover, it also tells you how a particular mixture of chemicals will react. This is because chemical reactions always occur in the direction which will make the ratio of their products to reactants equal to the equilibrium constant.…
