    Very cool. I have about 150 strips of paper thin Ti sheets that I purchased at an auction last year. I'm very much looking forward to your upcoming videos.
    By the way, I just uploaded my sub for science video. It should go public in a day or less.

    long story, i'll cover it in another video.
    Bottom line, titanium is clean, doesn't corrode, is physically stronger than other metals, and cheaper than pure platinum.

    This sure was reassuring. I just bought a titanium anode coated in ruthenium oxide and iridium oxide. They cut it from a larger sheet, so the side has exposed titanium. I was worried that this would cause the whole thing to slowly dissolve, but the passivation will prevent that.

    i included subtitles for those that have trouble understanding. Just click the "cc" button in the player bar. If the voice itself is grating (as i have been told) then just turn off the sound and use the subtitles exclusively. there is also a transcript option youtube provides so you can read the subtitles and skip ahead to the more interesting parts of a video.

    @nobox7
    It can be done, but i from what i understand it's not a good idea.
    i think a problem with platinum coating copper is that if you have even a tiny crack in the platinum it starts to corrode the copper in that crack. the corrosion spreads underneath the platinum layer and eventually dislodges the platinum. Titanium on the other hand just passivates itself and stops further corrosion.
    Better option might be to fill a titanium tube with copper and then platinum plate that. less resistance

  • @NurdRage
    @NurdRage  15 лет назад

    @NOBOX7
    Copper corrodes very easily if used as an anode, disintegrating with prolonged use. The conditions around anodes are very harsh and only a few substances, titanium included, can withstand them.
    Therefore a titanium substrate is preferable to a copper substrate.

    @electrosphere75
    titanium was scrap off ebay. $45 for three large strips.
    platinum electrode was a donation, but it costs the original buyer $150.

  • @NurdRage
    @NurdRage  15 лет назад

    oh electrolyzing water is just a demonstration. The video was about showing how titanium passivates if used as an anode.
    i'll be doing electrolysis in a later video

  • @Chemateur
    @Chemateur 15 лет назад

    @Hydroxybenzeen, you're absolutely correct, but I think antiswatt2 is talking about a stoichiometric mixture of hydrogen in oxygen in the balloon, which makes the reaction of hydrogen more explosive and makes the balloon experiment more impressive than pure hydrogen. A lot of people incorrectly label this mixture as H2O gas.

    You should use MMO coated Ti or Ni anodes and platinum cathodes for the electrolysis of water. The MMO coating aids in the formation of O2 while the platinum aids the formation of H2. Commercial electrolyzers use this method to improve production. The MMO coating is made of oxides of metals such as manganese, tungsten and ruthenium, according to what I've read...

  • @zerolabs
    @zerolabs 15 лет назад

    Excellent demonstration.

  • @NurdRage
    @NurdRage  15 лет назад

    Passivation can be done by anodizing, but not all anodizing leads to a passive surface.
    i'm demonstrating in this video the blocking of current due to an inert layer of titanium dioxide forming, passivation.
    While it is anodizing, giving this a title of anodization would be more misleading because that's not the objective.
    Kind of like drag racing, it's true that it's "combustion of gasoline" but that's not the objective, better title is "drag racing" or even "organ donor tryouts"

  • @ArnoldsDesign
    @ArnoldsDesign 15 лет назад

    Anodizing, cool. Have you done experiments varying the voltage to create different colors? There is an artist who uses platinum as his canvas. He uses a brush connected to the cathode. Through varying the voltage, he can "paint" different colors on the titanium. He has also experimented with various electrolytes. I wish that worked on aluminum.

  • @NOBOX7
    @NOBOX7 15 лет назад

    hey friend ,, great vid , i have a question though, in my past experance i have found that resistance heating of electrodes made of metals other then copper can cause excesive heating with only 10 to 15 amps at 12 volts, plastic melts at the temps i have observed in open bath testing, so my question is why not plate copper electrodes ,, im shure u have a very good reason for the titanium , i just wanted to tell you about the problems i have noticed during many test

  • @NOBOX7
    @NOBOX7 15 лет назад

    thanks for the info and just so im clear i was asking if it is possible to plate copper with platinum, i am aware of how fast copper corrodes in a cell but im intrested to no if i could possibly make my own platinum plated copper plates for an oxyhydro torch im building,,, you see ss steel gets very hot ,, up to 210 watts of heat is lost in just 6 inches at .02 ohms as a result of using stainless steel . but if you no a way to plate copper with platnuim it would be an amazing find for me ...

  • @Hydroxybenzeen
    @Hydroxybenzeen 15 лет назад

    @antiswattt2
    The explosive gas we are talking about is a mixture oxygen and hydrogen, mixed in stoichiometric ratio's (2:1, by volume). Steam will not do a thing. Yes ok you can blow up a balloon with steam until the pressure is big enought to make it pop. But that has nothing to do with the "explosive gas" .
    In my preveous post you can see the equalation of the reaction of the electrolysis of (acidified) water.

    Maybe he means H2O2 (Hydrogen-Peroxide), but you cant just put some electrodes in water to make it. That just produces a mixture of Hydrogen Gas, and Oxygen Gas. (Which is still an explosive mixture)

    I have been successfully using titanium foil as an annode conductor in a precious metal recovery copper sulphate parting cell. I can't say that I have witnessed this degradation of its performance. I would like to know how to recover the metals and sulphuric acid from the nickel fouled solution however. I've watched your video on separating the copper from the copper sulphate, and understand the need for a platinized electrode in that operation. That leaves the nickel, and possibly tin from the plated phosphor bronze e-scrap.

  • @jaceshigh1
    @jaceshigh1 12 лет назад

    I wonder whether electrolysis of water could be be achieved using A/C current with one titanium electrode and say nickel or stainless steel for the other electrode / neutrals. I would like try HHO for glassblowing but from the reading I've done so far producing enough gas could be difficult. I thought it may be more efficient to use AC and also lower capital investment but apparently it cant be done as any gas produced converts back to H2O b4 it can dissipate away from the electrode.

    @20kilovolt
    i suppose for academic interests you could make the equivalent of a diode with this.
    But as you've said, the equivalent reverse leakage, parasitic capacitance, forward voltage drop and resistance are all terrible. A diode hacked out of a radio performs better than this setup.

    Okay I'm very ill so I can't do this myself but. I recently had a lab accident while decarboxylating salicylic acid I had a break in a piece of glass tubing causing a salicylic acid energetic burst that got all over glassware and some metal tools. I can't get this material my glassware or the metal with any chemicals scraping it is almost impossible it it's as if it turn to glass.
    I have successfully made these electrodes before using manganese oxide excetera they work fairly well but do degrade in time which is a pain in the neck. I would love to see someone try to use both phenol and salicylic acid in one of these manganese or cobalt recipes to see if it extends the life of these electrodes and their coating.
    I don't know the state of decarboxylation I believe the liquid that spattered on everything was actually phenol but it could have very well come from the other side of the reaction and then simply molten salicylic acid. Whatever the substance is it is incredibly resilient. I would love to see nurdrage try this and let us know if it does anything again I'm very sick I'm fighting a terrible illness and it puts me down for months or I do it myself.

    is this how titanium is prepared for surgical implants? dental implants?
    have read some titanium implants work well with bone while others become problematic. biocompatibility is the term used.
    does titanium coated with titanium dioxide become less or non active in humans?

    is this the same effect that pure aluminium exposed to air passivates by forming a layer of aluminium oxide ?

  • @staszek300
    @staszek300 13 лет назад

    Hi. Could you tell me: If i want to make KClO3 I must have a steal cathode and titan anode. A titan anode must be covered a layer cobalt oxide or manganese oxide? Cheaper for me is of course covered titanium anode cobalt or manganese oxide to protected the titan to passivated. What voltage must be keep? 5 V will enough?

    • @SN2D
      @SN2D 6 лет назад

      Anode is to what the negative charges are attracted to and the kathode then the positive. If you are speaking of the technical flow of current it is swapped, that means you are assuming positive charges are moving in the medium, which is physically not possible, but was the one beeing set as standart back in the old days
