    Magnesium goes black?

    I have been experimenting with hydrogen water using a test tube with Malic acid and a pure magnesium rod. The reaction produces hydrogen but the rod forms a black coating. This limits the reaction time, but what magnesium compound is black? I use tapwater so iron might be involved and chlorine too. (There was a published study using hydrogen water to improve type two D)

    I found this old reference about the reaction of magnesium with organic vapors. Maybe you decomposed the malic acid to some sort of black carbon compound.

    Sometimes very tiny particles of either metals or metal oxides can look black.

    Beyond that, I don't know exactly what is going on. For one, what is "hydrogen water"?

    Hydrogen water is normal water that has molecular hydrogen dissolved in it, similar to CO2 dissolved in water to make carbonated water. Apparently it's a new health fad. Proponents claim it has a variety of benefits such as reducing inflammation. There is little to no evidence to support the claims.

    It is not my intent at all to suggest that the OP thinks any such thing. Just relating what little I know about hydrogen water.

    Perhaps manganese? My well water is heavy with it, as well as iron. The system prefilter is black with ‘em.

    profloater. Scrape some of the black coating off with a razor blade, box cutter, or sharp knife. Add to a clear glass container, with Distilled water only, and some white vinegar. The acetic acid in the vinegar will dissolve it if iron, making a reddish-yellow tinged solution. Then add some fresh tea. the tannic acid in the tea will preciptitate iron tannate, which is how American colonists made cheap ink. It's black.

    Thanks, I will try that.

    Thanks, the malic acid could form carbon, I guess, I did not expect that in the half equations.
    Well, I heard about hydrogen water or hydrogenated water at Christmas and had to look it up. I found a reference to Japanese research. It is apparently known in Japan as a medicine. The study is easy to find searching "hydrogen water diabetes" or I can post a link. In the published study type 2 diabetes patients made significant improvement after 90 days drinking the stuff. You can only get about 4 ppm in cold water and it then has a slight acid taste. It's new to me but there are other references and several to products in the US that you add to the water supply (electrolysis). I used the malic acid method for cheapness. I put a test tube with a leaky cork into a closed water container, about a pint at a time. In the fridge it takes half an hour to work. I control my type 2 by diet only and this might help, maybe.

    Yes we expect to find manganese with iron in the tap water and it may react with the malic acid. It's very black, so maybe it is carbon as Swift suggests. If it is carbon the rod should keep working, I guess, as an electron donor, but it's easy to scrape off.

    I scoffed when I heard about it, but felt obliged to check, and there is at least one human study from Japan and others in animals. If I survive the experiment I hope I can report back!

    the reference above is to the Japanese paper I mentioned.

    Fascinating! I'll definitely keep an eye on this thread. Best of luck.
