OK real simple, I not the type to flame a 13 old i was handlng fuming nitric acid when i was in pullups
ok 2 possible methods both require a plating power supply around 3 to 5 volts at 10 amps and some not so cheap and easy to get supplies....
first is the kestler ckline methiod: (well sort of) get a volume of mercury metal placed in the bottom of a pyrex container enough to at least cover the entire bottom of the container make the mercury the cathode (lower an insulated wire with a short striped end into he pool of metal) next you will need an anode preferably MMO coated Ti, but carbon/ graphite from a dry cell battery will do. then add saturated sodium bi-sulfite to the cell and turn on the power, the the sodium metal will plate into the mercury and the SO3 ion will be free to rip appart a nearby H2O making the acid.
(OK i know mercury is hard to get, I had to mine the 100 lbs that i have and retort it from raw sulphide ore(cinibar), took weeks of tinkering)
after some time the mercury will saturate with sodium, no problem, just decant the cell and rinse the acid off the top by over flowing the container, leave clear water in the container and stir until the all the sodium leaves the mercury making aqueous sodium hydroxide another nice chem to have!!! with this cycle you can work your way to most any inorganic acid directly or indirectly
the second in membrane electrolysis:
you will need a container that can be divided into to compartments by a membrane, with an electrode on each side of the membrane, ok so its a simple membrane cell you can google for ideas same voltage as above use a graphite or MMO Ti anode and the cathode can be any type of stainless steel (as long as you keep the power on when the cell has brine in it)
the only 2 possible membranes that i know of that a kid could get that will have any chance of sucess will be the following:
1. the seperater membrane found in the common DEEP CYCLE car style battery
2. DUPONT NAFION
3. TCF from a reverse osmosis membrane cartage
ok you mentioned fuel cell experiments, your fuel cell if its all plastic could make the acid just fine...........
OK everybody start making fun of my typos, i dont care....tata
