A method is described for determining the diffusion coefficients of small solutes in limited volumes (approximately equal to 4-9 ml) of fluid. Diffusion is measured in a three-chamber diffusion cell across a central unstirred compartment. Compartments are separated by nitrocellulose membranes. The i
Complexation of poly(vinylpyrrolidone) and gelatin with certain metal chlorides (HgCl 2 , CdCl 2 , CoCl 2 , and ZnCl 2 ) have been investigated by viscosimetric and spectrophotometric techniques in aqueous solutions.

The unperturbed dimensions and thermodynamic parameters of poly(vinylpyrrolidone) (PVP) have been studied in aqueous salt solutions, e.g. phosphates, mono-and dihydrogen phosphates, carbonates, sulphates of sodium and potassium. Values of where is intrinsic viscosity at # the theta temperature and
