Abstract
A Taylor dispersion method is used to measure ternary mutual diffusion coefficients (D11, D22, D12 and D21) for aqueous solutions of CuCl2 (1) + caffeine (2) + H2O-(3) at 25 °C and 37 °C at carrier concentrations from (0.000 to 0.020 mol dmâ3), for each solute, respectively. The results are compared with these obtained for the binary systems, that is, CuCl2 (1) + H2O (2) and caffeine (1) + H2O (2), also reported here. From these data it is possible to make conclusions about the influence of the caffeine solutes in diffusion of copper chloride.
