Abstract:

We consider an influence of the solvent ionic strength on thermodynamic properties and conditions at the onset of instability of a monodisperse colloid, as well as on the coefficient of mutual Brownian diffusion of colloidal particles. Special attention is given to collective effects due to competition of the particles for ions to be adsorbed, which are proved to lead to a noticeable drop in the particle electric charge and potential as well as in the ionic strength outside the double electric layers. An increase in the ionic strength above a region of relatively small electrolyte concentrations favours the phase separation of the colloid under otherwise identical conditions and causes the mutual diffusivity to markedly decrease, the more so the larger is the concentration of the particles.
