  • Separate Hydrogen and Oxygen from Water Through Electrolysis

    Electrolysis of brine is a chloralkali process and proceeds according to the reaction: 2NaCl + 2H2O → Cl2 + H2 + 2NaOH That is, hydrogen and chlorine are produced in equal parts. But because chloride is oxidized to chlorine more readily than oxide or hydroxide are oxidized to oxygen, no oxygen is produced from the electrolysis of brine.Much of the chlorine produced at the cathode, then reacts with the remaining sodium hydroxide forming sodium hypochlorite (aka bleach):Cl2 + 2NaOH → NaOH + NaClO + H2OTable salt dramatically increases the conductivity of the solution, thus allowing much more current flow which can make it seem like you're producing lots of gas, but you're mostly making chlorine and hot bleach and half as much hydrogen as you could be getting.

Bottom like NO CHLORIDES! You're better off using baking soda or washing soda or even lye and increasing your supply voltage until you get the results you're after. PS: if you can't find big enough carbon electrodes, you can also use lead.

  • How To: Make A CRT TV Into an Oscilloscope

    Try connecting a "dummy" coil to the disconnected output. Try to choose a coil of similar impedance to the yoke. (1-2mH, 5-10 ohms).Next time try using a small black and white unit. The simpler the better.
