    Hey Sci Guys, love the vid. Two questions: first, what do we change so that we get oxygen being produced on one spoon and hydrogen being produced on the other? Second, if we replace the spoons with strips of aluminum or nickel, will we still get a precipitate? Thanks in advance.

    I have a question. there will be a product of sodium hydroxide aka lye in the electrolysis of salt water but what would happen if you use the sodium hydroxide solution produced earlier for electrolysis? and what would be the products if you use that sodium hydroxide?

    can we separate carbon and oxygen in carbon dioxide using electrolysis?

    Say we dilute CO2 in water, then perform the same procedure from this video,. would it work?

    When you put rusty objects in vinagre, you also get H2? Or/and something else?

    Is there another electrolyte which is not salt that would allow for the oxygen and the hydrogen to be left alone to themselves? What I mean is that I'd just like to collect the hydrogen and the oxygen in their pure elements, nothing else. (doing this for a mars colonisation project)

    I want to produce only hydrogen gas and oxygen gas so what kinds of electrolyte's r good and for this what kinds of electrode is good

    Question: I'm now conducting an experiment that studies exactaly what concentration of NaCl will cause the production of chlorine gas. I used graphene electrode in order to avoid unknown products. However, the cathode starts producing greenish precipitate after the NaCl concentration exceeds 3M. I'm wondering if that's related to chlorine gas, but I get pretty confused, becuase 1. chlorine gas should be produced in the form of GAS not precipitate 2. Chlorine gas should be produced at the anode.

    Please help me out! Thanks guys!

    You could use bakeing soda instead of salt. With baking soda there is way less corrosion and less acid

    How can you exactly measure the gases produced in electrolysis of water?

    I'm assuming the spoons are stainless steel?

    If so, the oxide might be a chromium compound of some sort

    Isn't chlorine gas green in colour so is that green colour of chlorine gas escaping?

    Not to confuse anybody.. but water is a covalent bond and in a textbook it says that if you pass an electric current through an IONIC substance. It breaks down the elements it's made of. Called electrolysis

    I'm not a scientist but I know that your confusing the people. Hydrogen is supposed to be represented as an white colored Atom. AnD Oxygen is supposed to be represented red.

    The way I understand it is that salt acts as a catalyst for the reaction and catalysts are not consumed in chemical reactions. additionally bases and acids react with each other and when you poured the vinegar into the base I didn't see a reaction. I'm not saying your wrong with how the molecules rearranged themselves I just want clarification.

    Can you please make another video explaining how to collect the H2 and Cl2 gases produced during electrolysis?
