    Jan 14, 2015 · $\ce {H_ {2}O}$ is the water molecule, two hydrogen atoms attached to a central oxygen atom, $\mathrm {C}_ {2v}$ symmetry, thermodynamically minimal structure of these atoms, Adam's …

  2. electrochemistry - What metals are safe to use as electrodes when …

    May 5, 2022 · I am going to be a DC power converter (with fairly high voltage and amps) to turn water into hydrogen (and oxygen) gases. However I have a few questions about the safety of this process. …

  3. Is oxyhydrogen lighter than air? - Chemistry Stack Exchange

    Oct 27, 2022 · This is a matter of simple calculation. If you don't know how to calculate it, then all this looks like just another reason not to anything like that.

  4. How does high-frequency electrolysis of water work?

    Feb 20, 2022 · I have read that combining the DC current with a high-frequency AC current, the electrolysis of water speeds up. Is this true? In that case, how is less energy wasted as heat? Or …

  5. Why is it OH- and not HO-? - Chemistry Stack Exchange

    I am told that in a chemical equation the metal comes first and then the non metal. for example MgO, ZnSO 4,etc. But when both the elements are non metals or metals, the one with the lower atomic …

  6. How explosive is hydrogen gas? - Chemistry Stack Exchange

    Feb 15, 2014 · I want to electrolyze water to get oxygen and hydrogen. I want to mix them in a regular balloon and ignite it. How much hydrogen would you need in a 2:1 ratio with air for it to be …

  7. Can natural gas appliances run on Hydrogen? - Chemistry Stack …

    Jun 22, 2013 · Pure hydrogen, as opposed to hydrocarbons, degrades metals. $\ce {H_2}$ molecules are tiny, so they wedge themselves into the relatively large metallic crystal structures and form …

  8. In my homemade electrolysis setup, only the negative end bubbles?

    I've created an electrolysis setup by connecting a $6~\\mathrm{V}$ battery to a cup filled with saline water via pencils; I am confused as to why only the negative pencil bubbles though. After runni...
