The
colloid-free solution obtained at equilibrium in
dialysis. Its composition approaches that of the dispersion medium (more precisely, the limit to which the composition of the dispersion medium tends at large distances from the particles). In the
dialysis equilibrium an
osmotic pressure difference exists between
sol and equilibrium
dialysate.
