Colloidal silver

A heterogeneous mixture composed of two or more substances with one substance being silver, wherein each keeps its original properties and the solute-like, suspended solid particles remain dispersed within a liquid without settling. A colloid of silver would suspend silver particles (dispersed phase) or a silver compound, such as silver oxide, most commonly in water (continuous phase). With elemental silver or a silver compound, particles may be neutral chunks of silver or they may carry an active electrical charge; negatively charged silver in nature is extremely rare. An electrical charge would commonly be dispersed dynamically across the surface of the particle.
