The diffusion coefficient of aluminum in mercury was measured over a concentration range ofo.9 to 14 mM. It was found to increase with increasingcodcentration from 1.2 x 10m5 to 1.9 x 10m5 cm2 seC'.
The diffusion coeficient, D, of CuSO, in aqueous solution was determined at 298.1 K by chronopotentiometry and also with a rotating disc electrode using the mixed control Levich equation.
