Jobs method of continuous variation explained

Web3 jul. 2024 · One such method, the Job’s method, is concerned with evaluating n for the equilibrium below. In this experiment Z is Ni2+ and L is the ligand ethylenediamine (en). Experimentally, the absorption at a given wavelength of a series of solutions containing varying molar fraction of Z and L is measured. Webequilibrium constant will be found using the method of continuous variation. INTRODUCTION The iron-containing species in the reaction shown above (see equation 1) are called complex ions. This class of reactions is often called complexation; it is an important class of reactions, particularly for transition metal ions.
