Video transcript

Well, everyone in this video, we're being asked what happens at the an old when molten KF is electoral. Ized. Let's go ahead and recall first that the cathode is where reduction occurs. And then for our a node, this is where oxidation occurs. Okay, so during electrolysis the cattle is reduced so it gains electrons while the an ion is oxidized, which means it loses electrons. So in the electrolysis of molten KF. So let's kinda actually write this out. So at electrolysis, r K plus ions are gaining electrons and it's being reduced two potassium in a solid state at the cattle while the flooring and ions lose electrons that are being oxidized two F 2. So back to its natural elemental state and this occurs at the so then at the anodes. So again it's at the anodes, this at the cathode. So we're dealing with of course our animals that were being asked. So at the anodes, we have the oxidation of f minus two F two and running out that equation, then that's two modes of f minus two, F two gas plus our two electrons. So then this right here is going to be my final answer for this problem. Thank you all so much for watching
