Using the eq constant 2.47E-6, check the assumption that all of the SCN^- was converted to FeSCN^2+ in tube 1. Assume that the value of [FeSCN^2+]at equilibrium is an unkown quantity x. Express the values of [Fe^3+]and [SCN^-]at equilibrium based on inital concentrations minus the amount that reached to form [FeSCN2+]. Sole the quadratic equation for x. What fraction of thiocyanate ion is accually converted into the complex ion?
