The formula of a complex formed by a reaction such as m nx, Ask an Expert

Academics

The formula of a complex formed by a reaction such as M + nX = MXn can be determined by the method of continuous variations. The absorbances of a series of solutions of varying composition are measured at the wavelength at which the complex shows its maximum absorptivity. The number of moles of M and X is kept constant, while the mole fraction of the reactants varied. The following data were obtained for the reaction of M and X. Solution A is 0.0100M and X ; solution B is 0.0100 M and X Sol.# mLA mLB Absorbance 1 10 0 0 2 9 1 0.133 3 7 3 0.4 4 5 5 0.667 5 3 7 0.932 6 2 8 0.8 7 1 9 0.4 8 0 10 0 Plot the absorbance vs mole fraction of the X and calculate the formula of the complex from the mole fraction at which the maximum absorbance is obtained
