RE: They assume because a solutions of Colloidal Silver that is not made with chemicals, and is clear as water is an Ionic colloidal solution.
> I agree with this. It is possible to have nanoparticles in suspension without any sign of colouration in cases where the particle density is not high enough refract light.
RE: It is impossible to make ionic silver without the use of chemicals.
> The chemical in this case is water. And cat-ions are water soluble and therefore diffuse evenly throughout the solution(by repulsion) due to their net positive charge.
