Please forgive me if this is under the wrong branch of science but I considered it to Be electrochemistry. I have been trying to build a hydrogen converter to get oxyhydrogen gas. I built my converter but had some problems, here was my setup: I used a plastic bottle, and drilled to holes in the side. In each of these holes a placed a stainless steel screw. I took 8 rechargeable AA batteries for my power supply. They are all rated for 1.5 volts but using my multimeter they were only 1.3( doesn’t matter too much to me). I put them in series and checked to see that they were 10 volts, which it thought would be good enough for splitting water. I used alligator clips to connect the positive and negative ends and I didn’t see anything happening. The water had baking powder in it, which has baking soda in it, which should conduct electricity. I tried putting a single 9 volt in and saw a bit of small bubbles forming. I was thinking that maybe there was not enough amps but I used my multimeter and it seas something like 10 amps. I also used my multimeter on either side of the circuit and it didn’t show any current so I was thinking maybe the gap between th electrodes was too far. But the i just put the alligator clips in a and still nothing happened. I have seen people on YouTube run these things off of 12 v car batteries and I’m only two volts away. I only have a basic knowledge of electricity and how amps and volts work and all that, so I don’t understand it very well, and was just wondering if anybody could help me out, Thanks!
