A system is regarded as in a state of equilibrium when it is properties usually do not change in time passes. Equilibrium is known as a state of any reaction in which the concentration of all of the reactants and the products stay constant after some time. Equilibrium while used in chemical systems implies that all the chemical forces in a reaction happen to be in balance and that most physical homes of the system (color, denseness and concentration) of all chemical substances species included remains constant. The equilibrium state can be characterized by quantitatively defining the equilibrium frequent, Keq. From this experiment the Keq intended for the reaction among iron (lll) ions and thiocyanate ions, SCN- is determined.
Fe3+(aq) + SCN- (aq) FeSCN2+ (aq)
The equilibrium continuous Keq, can be defined by the equation;
Keq= [ FeSCN2+] / [Fe3+] [SCN-]
You need to determine the molar attention of each with the three kinds in answer at balance to great the value of Keq, which depends only upon temperature. So as to have a successful analysis of this equilibrium system, it is crucial to conduct three testing separately. This kind of experiment is completed into two sections. First, from the series of standard solution of FeSCN2+ was ready varying attention of SCN- and constant concentration of H+ and Fe+ which have been in stoichiometric excess. The excess of H+ ions will make sure that Fe3+ has no participate in the reaction and excess of Fe3+ ions could make the SCN- ion the industry limiting reagent. In part lmost all the solution of unknown [SCN-] was evaluate using the same procedure as in part t.
