Well That's why I thought a thought provoking project, I learned in class of Oxygen's tendency to bond to positive ions, so I though lets put this idea through a test. And please cite a resource for your belief since It can be incorporated into my hypothesis and so that I can show it to my teacher too, Thanks a million!!

You will have do do your own literature work as it is your idea not mine, so you will need to find evidence to support it yourself.
