When a fish starts hittin puberty.... The voice...

btw thats 1.7 miliohms shunt resistance and 54 milivolts of shunt reading. since I need to divide miliamps/cm^2 I need to friggin multiply by 1000. The shunt was checked for calibration drift before running the cell and due to my awesome cursed crimping job it holds up to the calibration!!

That is badass! I need to build a perchlorate cell soon.

you would need to modify an MMO anode to support PbO2 for best results. or get your hands on tin nitrate and dope it with antimony or bismuth or manganese for the precoat. ofc you need a Ti electrode either way if you are gonna go the 2nd route.

I have a small mmo and titanium electrode unit. The only manganese source I have right now is the pounds of KMnO4. Any way to use that, that you can think of? I have lead and everything to make the PbO2.

@@chemistryofquestionablequa6252 you can do 2 things here. the KMnO4 can be made into a solution and you can use a titanium electrode as a cathode and a layer of MnO2 will deposit on its surface. you then bake that electrode at 400 Celsius to convert the MnO2 into the conductive form. then you plate it in lead perchlorate to get PbO2. If you want to convert your MMO into PbO2. The MMO can be first plated in lead acetate for 15 minutes at 7 minutes per side at a current density of 6ma/cm^2 at 40 Celsius. The electrode is then plated in lead perchlorate/chlorate at 8ma/cm^2 at 40 Celsius for 12 hours to get a thick coating of PbO2. A converted MMO can be used to run chloride all the way to perchlorate but errosion will occur until equilibrium since PbO2 doesnt like high chloride environments. Lead perchlorate/chlorate can be made with a membrane cell and lead electrodes and you can also use lead nitrate but the bath temperature must be higher like 60 Celsius. surfactants are also important here and the best to use is benzalkonium chloride which can be found in the nail polish remover section right next to the acetone in the grocery. There are other surfactants like liquid hand soap which also can be used and is suggested to prevent lead salt spray during plating which is really bad!! for lead perchlorate you can immerse lead metal to regenerate the plating bath continiously.

@MysteriusBhoice thanks for the thorough rundown of the processes. My mmo unit is bonded with plastic and white small to be inserted in a bottle to make disinfectant. I don't think I can heat it to 400c. I'm going to have to buy a cheap platinised electrode, or go the route of PbO2 on carbon I think. I'll definitely have to try your methods when I can. We have a new baby, so free time is in short supply, lol.

Thanks brother,, that would be incredibly helpful!

how did you calculate the effective area of the mesh?

@CatboyChemicalSociety

9 ай бұрын

For these it's 1:1 because what u can do is because the thickness of the mesh is 1mm it means each hole has extra 1mm of flat surface. If the gap of each hole is also 1mm on average then you have 2 of these 1mm inner surfaces projected upward meaning it's 1:1 to a flat plate. If the dimensions are any other then you can also use resistive means to measure it's effective area using NaOH as electrolyte and steel as the anode and a Ti strip of known area as the calibration cathode.

@@colin351 you cant use stainless steel in a perchlorate cell without platinum electrodes. It will leach chromates killing you anode's surface activity. The stainless steel can be copper or nickel plated though to prevent this. copper and nickel cathodes work too for perchlorates. Titanium id say is a good cathode but shitty if you think about it because its not easy to plate Ti electrode contacts with copper as compared with anything else. stainless steel can be used for chlorate production since chromates are not a problem there.
