Summary Volumetric measurements of ethylene and simple EDTA titration of copper(I) and copper(II) ions confirm that [CuL]+ and [CuL2]+ are formed when an aqueous solution of copper(II) is reduced by copper metal in the presence of ethylene, (L). The formation constants,K 1=[CuL+]2[Cu2+]−1[L]−2 andK 2=[CuL 2 + ]−1[L]−1, have been estimated. The formation of [CuL]+ is accompanied by an enthalpy change, ΔH, of −25 kJ mol−1, and a positive entropy change, ΔS, of 13 J mol−1 K−1.
