KOH VS. Baking Soda, etc.

[HHOhoper]

I've heard that KOH is by far the best choice for electrolytes due to it's performance. I went and tested my dad's cells. He has two cells in series totaling 7 amp draw and putting out a sad liter per 8 minutes and at 135 degrees. The best I've done on mine is one liter per 5 minutes at 17 amps and 120 degrees.
I'm telling him that I've heard that KOH is the best only because of what others say, but I personally don't have any experience. I know it's toxic, but does it corrode engine parts like some say?

Will KOH provide more production than baking soda at a lower temp and lower amp draw?

What are all the downsides to KOH that you can possibly think of?

im not so clever in chemistry,can i know KOH similar item that we can buy that we use daily like?

I tested baking soda, sodiun hydroxide. and potassium hydroxide.

Potassium hydroxide is by far the best. The reason is rust or crud generation.
Baking soda is worst, changing electrolyte every 2 days. Sodium hydroxide is better, changing electrolyte about every 5 days. Potassium hydroxide, has barely any generation of crud. It has been weeks and I only have to add distilled water.

It does not harm your engine because it stays in the electrolyte. When the water is used the electrolyte gets stronger because the potassium hydroxide stays in the electrolyte. I've only added distilled water to my HHO generator for weeks.

Potassium hydroxide is caustic, and the crystals are dangerous, so care should be taken when using it.

Potassium hydroxide can be bought on ebay or AAA chemicals.

That is VERY helpful information; thank you! Now can anyone provide information about how Potassium Hydroxide, Sodium Hydroxide, and Baking Soda all compare when it comes to comparing hydrogen generation against how much heat is generated and how many amps are required?

For example: If you were to conduct an experiement using all three electrolytes and you adjust each to only put out 500ml per minute. How hot would each get and how many amps would each draw?

HHOhoper,

I never did any metered tests comparing the 3 chemicals. But my general observation is that they were close to being the same for a given power level.

Potassium hydroxide is SO much better because you can run for weeks , and only add distilled water to top it off as the generator uses it. I actually don't know how long it can run without changing, because I haven't had to, and it's been weeks. The crystals are caustic so be carefull with them.

Baking soda sucks worst, in 2 days I can't see the electrodes, and have to pull the generator out of the car, dump it in the sink, and make new electrolyte, then put it back in the car.

So is the only advantage to KOH, the cleanliness of it in a cell?

Now are you talking about Potassium Hydroxide Flakes or Potassium Hydroxide Lab Grade?
