Diffusion of Heavy into Light Water

We have made measurements of the diffusion coefficient of heavy water (0.5–3.0 mol per cent) in aqueous solutions. The value provisionally obtained is about 9 × 10−4 cm.2/sec. at 15° C. Since this is appreciably greater than is to be expected from the mass diffusion of water molecules (the largest recorded diffusion coefficient, namely, that of H2 in H2O… (More)
