Can the 4 electrons gained in the anode reactions be reused for the extraction of Al in the cathode reactions? If no, why?
@jgkg10
7 жыл бұрын
Hi Kosal. The electrons lost by the two oxide ions at the anode drift around the circuit and eventually would be used at the cathode for the reduction of the aluminium ions. These electrons are not 'lost' but simply form part of the overall flow around the circuit.

In my book it says they used graphite as cathode and graphite rods dipped in molten mixture of electrolyte as anode? Why u used carbon in this?
@jeremygibbon7080
5 жыл бұрын
Graphite is just one particular allotrope of carbon, so in a sense it is saying the same thing. Carbon is the element that the electrodes are made from. The particular form of carbon (allotrope) is called graphite. Their shape and what they are treated with then is described in your book correctly. Hope that helps.

Hello Mr, I have got a question and I wish you could help me. Why is NaOH used?
@jeremygibbon7080
5 жыл бұрын
Hi. Basically the NaOH is used to purify the bauxite (in something called the Bayer process). The oxides of aluminium dissolve in the hot NaOH. The impurities (mostly iron oxides) don't dissolve and are removed by filtration.

This is an educational video, why is that even significant. It is a meaningless micro detail which doesn't actually serve any educational purpose to the audience the video was meant for. What is important is the MASSIVE amount of current needed, due to the 3 electrons needed for every atom of aluminum.(Actually 12 electrons are needed for 4 Aluminum atoms)

Yes, agree. I use the term carbon to refer to the element the anode/cathodes are made from, rather than the specific crystalline form of carbon called graphite.

Hi. Each half reaction needs to be balanced in terms on number of particles (atoms or ions) on each side and the total charge on each side. Once the half-reactions have been balanced, then if you need to combine to show an overall reaction, then the number of electrons in each half reaction must be balanced before adding them together (so that the electrons cancel). The cathodes reaction uses 3 electrons and then anode reaction releases 4 electrons. To balance this we multiple through each reaction to create the same number of electrons (in this case the lowest common multiple of 3 and 4 is 12). Therefore we want each half reaction to end up with 12 electrons. To do this you multiply the top one through by 4, and the bottom one through by 3. Does that help?

Just had to add the "indoctrination" to the political issue of "climate change" (wasn't it global warming) at the end, didn't you? CO2 is NOT a TOXIN. It makes the PLANTS GROW.
