| It is possible through advanced mathematical computations to isolate information about pure chemical compounds without isolating the compounds themselves. Sivvu is a set of Matlab GUI Protocols that use Equilibrium-Restricted Factor Analysis to model the spectrophotometric data of multiple equilibrium solutions and solve for the molar absorptivities of all the species in the solutions as well as the thermodynamic parameters that govern the equilibrium reactions. By titrating a bromide solution into nickel(II) solutions with γ-butyrolactone as the solvent, the wavelength dependent color of [NiBr]+, [NiBr2], [NiBr3]-, and [NiBr4] -2 have been elucidated, along with the Gibb's free energy terms for the stepwise complexation of bromide to the metal cation. |
