I think a suspension would be more apt. Silver oxide and silver hydroxide will form a suspension, but it will fall out and go to the bottom since it is lacking in zeta potential. I think the term colloid refers to a suspension that does not settle out. > > Next questions: Can such a molecular structure consist of both molecules > in one crystal and can peroxide scavange one away and/or the other and > break the crystal apart while producing metallic silver in the process? I believe it can if I understand you. I think you are asking if H2O2 and Ag2O can react to form Ag2 and H2O and O2 if the silver oxide is in the form of a precipitated crystal. I believe that is one reason why H2O2 can clear a milky CS so quickly. > > > What role could suspended oxides in such a crystal play in 'shades of > black' darkened tints of a color produced by particle size? aka "tea" colors. First you have to look at the solution and see if you are looking at a clear liquid that is absorbing light at certain wavelengths, or something that is milky and reflecting light of certain wavelengths. The color of the first is caused by a colloid of fairly large particles that are absorbing in the violet and blue range. The second by a suspension of silver oxide and silver hydroxide particles that are brown colored. However if you let it set, the second particle should eventually settle out, only leaving the true colloid of silver particles. > > > It is possible that "particles" can be too small for a laser to 'see'.

Atoms and ionis yes, but I believe that an aggregation of 2 or more silver atoms will scatter light. If you add H2O2, I believe that the particles will be 2 aoms each, yet you can still get some tyndall with it.
