Thread: The BEST electrolyte mixture.

  1. Lightbulb The BEST electrolyte mixture.

    It has been demonstrated that a 27% KOH/Water electrolyte is the most efficient formula for making Hydroxy.

    Wouldn't it be great if this became the standard by which all experimenters could compare results?

    Here's how to make it:

    Take a CLEAN vessel and add 730 ml of pure distilled water. (24.68 oz.)

    (Don't treat your cell worse than your car battery.)


    SLOWLY add 270 grams of KOH. (9.5 oz)

    Stir with a CLEAN stirrer.

    Be careful.

    At that point you have the best mix for a cell.

    Anything after that is because of your design and technique.

    Can you get us the details of how you determined 27% KOH is best?

    Someone should make that mixture and stick it in their freezer to see if it freezes! I would, but I have no KOH.
    Give a man a match, and he’ll be warm for a minute, but set him on fire, and he’ll be warm for the rest of his life.

    No, what I wrote is correct.

    Remember, 730 ml of water is also 730 gm of water.

    Since KOH comes as a crystal and its density is not 1 gm/cm^3, weighing it is the correct way to use it.

    If you add 270 gm of KOH to 1,000 gm of water you will have 1,270 gm of a mixture.

    The concentration of KOH will then be 270/1,270 or 21% and not 27%.

    You're right about that, I changed my earlier post accordingly.

    27% KOH sounds like a lot!

    Where did the # of 27% come from? I ask as I have a chemical mixing plant down the road that specializes in high end industrial cleaning. I am able to have them precisely mix what ever % of KOH I want. Might be worth talking this over with their chemist to see what he thinks would be best.

    I'd be willing to experiment, but would like more input from you guys here as to what you think a good start point would be and how high I should push it up. As I would have it professionally mixed, I would also have analysis information to go with this.

    Tell that to NASA, Bob Boyce, and the other giants in Hydroxy.

    Your grandmother may have used it with grease to make soap.

    Biofuel guys use it with used veggie oil.

    Look up biofuel.

    BTW 2nd choice electrolyte is NaOH.



    The mixture is not 27%.

    I believe that it may be 30%. Not sure. Google, etc.

    3rd and worst (like in do not use) choice is Sodium Bicarbonate (Baking Soda). You will have to figure that one out for ourself before you pollute the environment.

    i use NaOH. haven't found a KOH supplier yet.

    my container takes 1L of water and i usually put 2 small coffe spoons of NaOH ( i guess maybe 10g ). more than that and i can not control temperature.
    i also don't have the means to control V or Amps. the cell "takes what it whants".

    so my question is, if i go for that NaOH concentration, and since the negative pole is the container itself, to control the temp, i should use a smaller positive plate ?

    thanks
