Can I use potassium fluoride for electrolysis? Instead of KOH, or NaOH. This cell will be operated @ near 90 C, so I want the graphite electrodes to last as long as possible. I just need to know if the fluoride ion can be oxidized in an aqueous solution...I know fluorine gas is usually generated with a molten fluoride salt, so I don't think it will happen in sol, but I'm not sure. I DO understand the toxicity of the compound... 245 mg per kg LD 50 in a rat...compared to NaCN's 9 mg per kg I just need to know if the fluoride ion is stable in sol, or not?
