    40 to 15 is not 2:1 Ratio of Hydrogen to Oxygen. It should have been 40 to 20 . GOOD Video !

      He realised that he didnt have 40 of hydrogen so he said hes going to instead do 30 so it would be 2:1

    Sir , Can i human use this oxygen , can a human inhale this oxygen . Please answer me

    if water decomposes then it makes 2 gasses at the point its being decomposed. Two different size bubbles would rise at the same time. How do the two parts get separated into opposite tubes in this experiment? Both sides would have the same HO gas. The qty of gas is not the same on both sides so therefore water is not being split.

      I am unsure if this is serious or not but to answer the question:
      Polarity and Molarity.
      In their ionic states Hydrogen has a positive charge and is drawn to the negative electrode, Oxygen has a negative charge and is drawn to the positive electrode. This is how the gases are seperated.
      The quantities of gas differ because both products are diatomic. Hydrogen is H2 and Oxygen is O2. A single molecule of water has 2 atoms of Hydrogen and 1 atom of oxygen. In other words, to produce a single molecule of O2 gas, two water molecules are decomposed. Or phrased another way, each molecule of water has twice the quantity of Hydrogen as it does Oxygen. Which is why their electrolysis will always produce the gases in a 2:1 ratio.

      @@BlackOctoberFox If the water was split both gasses would be present since they both make up water. Both bubbles would rise up on both sides. This is obvious! I don't see bubbles moving across to join their respective gasses! Therefore water is not being split. The electrode/electrolyte must be making the O and H. The single gasses rising on each side is visible in the experiment. (PS water is an element and cannot be split).

      @johnnym6700 Right. Well that confirms it. You're either an idiot, poorly educated, or trolling.
      1. Water is not a Chemical Element. It is a molecule composed of the elements Hydrogen and Oxygen.
      2. The gases are propagated at the respective electrodes. The electrode simply serves as a way to deliver an electrical charge and does not react with the solution whatsoever. Why the gases form where they do is related to ionic charges. For the sake of simplicity think of it like magnets, the Oxygen has a negative charge and the Hydrogen has a positive one.
      3. Both gases ARE present. But they ARE seperated.
      I quite literally performed this experiment today, hence why I was looking up the video, not only is the displacement in a roughly 2:1 ratio as one might expect, but simply testing the gases with a splint or match confirms the presence of Hydrogen at one electrode and Oxygen at the other (Hydrogen combusts with a loud pop, Oxygen will reignite a smoldering match) Furthermore, you can confirm the water as the source of the gases because it decreases in volume as it is electrolytically decomposed. All of this is clearly visible and explained in the video.

      Hydrogen is a Positively Charged Atom, and "Opposites Attract", So, the Positively Charged Hydrogen Atom is attracted to the Negative Electrode in one glass tube.... Oxygen Atoms are Negative Charged Atoms and again, (Opposites Attract ), so, the Negative charged Oxygen Atom is attracted to the Positive Electrode in the other glass tube. This is how the Water Molecule is pulled apart using electricity submerged in the water. This is also how the Hydrogen Gas is kept separate Tubes from the Oxygen gas. Water is H2O, which means that the Water Molecule contains Two Atoms of Hydrogen, (H2), and One atom of Oxygen Gas, (O). When you split the Water Molecule using the process of Electrolysis, in separate tubes (which are connected to each other by the Horizontal connecting tube), you will have 66.666% or two thirds Hydrogen gas to 33.333% or one third Oxygen Gas in separate tubes. Water is a poor conductor of Electricity So, You must also add a small amount of an ELECTROLYTE chemical, like LYE or Sulfuric Acid to increase the conductivity of the electrical current flow through the water between the positive and negative electrodes.

      @@gasolinevaporsystems9022 you would have two lots of gas bubbles at each electrode which would float up together at the same time. One bubble would be oxygen and the other bubble would be hydrogen. We don't see some bubbles swapping sides LOL. A one year old could figure this out. This doesn't happen therefore water is not being split. Are you still following me? or is this far too complex for you to understand?

    is this oxygen inhalable safe for humans??

    • @lautaromorales2903
      @lautaromorales2903 Před 3 lety +2

      as long as the water doesn't have chlorine ions that can be electrolized to chlorine gas (like in tap water), only pure oxigen is produced, that indeed, is safe to inhale

    • @lautaromorales2903

      the only thing that you can't do is inhaling 100% Oxigen for s long period of time, because it's toxic yo humans in that concentrations
