Hildebrand equation

WebScatchard published a paper in 1931 which, in his words, "may be regarded as a quantitative development of the treatment of Hildebrand, although it disagrees with his ideas in some important details, or as a method of freeing the van Laar treatment from the inadequacies of the van der Waals equation." Hildebrand and Wood derived the same ... WebUsing the Beer–Lambert law, the equation can be rewritten with the absorption coefficients and concentrations of each component. Due to the previous assumption that [G] 0 >> [H] 0, one can expect that [G] = [G] 0. Δε represents the change in value between ε HG and ε G .
