  1. Melvin, isn't potassium dichromate in HeadOn? I remember reading it there... Quite convenient... But my graphite electrodes began crumbling. Then later when I shorted them for fun they exploded, so... Either way they hardly work. Would a gold plated usb thingy work? Just ripping out the plates...

     

     

     

    mmm ill just rip open a car battery! oh and I have some chunks of lead. can't I just throw oxidizers at my lead chunks? oh and would bismuth work?

     

    A car battery has lead dioxide rod in it but i've heard that the coating isn't good and will come off. Using lead anode and cathode in a nitrate solution just grows cyrstals on the anode. So the previous method is the best get copper nitrate at united nuclear and lead nitrate at ebay "remember these are toxic chemicals". Don't think bismuth will work.>:D

  2. I saw a couple of threads with people asking about chlorate related questions so heres a guide roughly based on wouters guide. Note:take the same steps as preparing potassium chlorate to prepare barium chlorate.

     

    1. Cell construction

    Anodes are the electrodes that don't bubble as much as the other electrode "the cathode". Since most metals will not produce chlorate when used as an anode only a handful of metals will work. Here is a list of all the anodes No other metal will work as an anode except for these.

     

    Platinum: Don,t waste this metal on chlorate production.

     

    Graphite or carbon rods: Graphite corrodes a lot especially when salt concentration's go down. Carbon rods can be dipped in linseed oil to work better.

     

    Lead dioxide: Mostly used in perchlorate making although can be used in chlorate making.

     

    Magenite: "Not sure if I spelled this right" this electrode barely corrodes even at low salt concentration's, but current efficiency will suffer when using this metal.

    Here are some rare anodes little info is known.

    Mixed Metal oxide

     

    Manganese Dioxide

     

    Spinal Cobalt Oxide

     

     

    Cathodes are the bubbly electrodes almost all metals can be used copper or titanium are good cathodes.

     

    2.Cell run time

     

    Well heres some basic time for production of sodium chlorate and potassium chlorate

     

    30 grams of NACI running at 0ne amp takes 6 days to convert

     

    30 of KCI running at 1 amp takes 4 days to convert.

     

    3. Removal of product

    Potassium chlorate will electrolyze at the bottom and top of the cell. This makes it so you will have to boil the solution and add water until all the chlorate is dissolved, then pass it through a filter to separate the corrsion stuff from the chlorate.

    If you make sodium chlorate just boil until cyrstals appear.

     

    4.Purifying the product

    To separate chloride from the chlorate wash the product with ice water "i've had trouble with doing this method"

    Another purifying method for potassium and barium chlorate is to recrystallize the chlorate to separate the chloride from the chlorate. Take 30 grams of crop per a 100 ml of water. Boil and add water until all crop is dissolved. Cool and crystals of potassium chlorate or barium chlorate should form. Repeating this is recomened.

     

    5. Testing for chlorate

    All chlorate react with sulfuric acid showing more then 20% of chlorate is present. Try a Google search for this because I don't have a lot of info .

  3. Well here are a list of anodes "the electrodes in the cell that dont bubble" that you should use. Graphite "very corrosive especially at low chloride concentration in the cell but makes chlorate ", lead dioxide its aslo called "poor mans platinum" works very well, although corrodes at low chloride concentration , but its hard to find. To make it you need to electrolyze a acidified solution of lead nitrate and copper nitrate the anode should then have a nice coat of lead dioxide. All those other metals you have will not make chlorate if used as a anode, but can be used as a cathode.:D

  4. If you want to make H2SO4, you need SO2.

     

    Unless, of course, you electroylzed CuSO4 solution (I would think the product would be contaminated, though).[/quote

    No I mean when S02 is absorbed and is some smoke of gases beside So2 is present when SO2 is being condensed will that make a weak solution.

  5. Im pretty sure this would work. You need a metal container "A old car battery or something thats resistant to sulfuric acid". A metal cover "make sure it fits the container" ,you will need to file some pennies until all the zinc is exposed, copper wire, and a drill. Drill a hole in the penny and thread the copper wire do this twice to make the anode and cathode. Fill the container with the sulfuric acid "be careful". Then drill a hole in the metal cover and thread the copper wire so that the penny and some of the wire is in the solution while some of the wire is sticking out. Put the metal cover on and your done. :D

  6. Ok i have two flasks both sealed and contected with plastic tubing, one under the burner that holds the HS204 and a little bit of salt, another that holds water both are humdfying and I think its working. How much salt are you supposed to use i only used a little bit.

     

    Is there any tests i can do with HCl than lithmus?
