Hi. I've been working on a project to find more modern and efficient ways to produce colloids for use in nanotechnology as well as medicine. My main preoccupation has been with hydrogen peroxide and its varied reactions with certain metals and metal salts to produce more long lasting suspensions. However, with recent experiments I found that a partially oxidized solution of copper particles in such a solution of hydrogen peroxide, will react with sodium bicarbonate to form a colorless solution. I have been unable to fully grasp what is occurring here, and so I ask, if anyone may have insight on the matter, to please enlighten me as to what is happening.
