Students are meant to discover answers for themselves, not just call up the aether and get someone else to do it for them. Electrolytic means the passage of an electric current; reduction means to bring down from a higher (energy) state to a lower (energy) state.

The current reduction process employs a platinum anode and a stainless steel alloy 316 cathode in a molten salt bath consisting of licl–2wt% li 2o and occurs at 700⁰c. A major shortcoming of the existing process is the degradation of the platinum anode under the severely oxidizing conditions encountered during electrolytic reduction.

•knowing that oxidation occurs at the anode and reduction occurs at the cathode it is possible to predict the electrode reactions in a particular electrolytic cell.
The three main components of electrolytic cells include the cathode, the anode, and the electrolyte. In electrolytic cells (as is the case in most electrochemical cells), oxidation occurs at the anode and reduction occurs at the cathode.

Electrolytic reduction (iii) electrolytic reduction the reactive metals (high up in the activity series) cannot be produced by any of the above methods. They are obtained by electrolytic reduction of their molten oxides or chlorides. During electrolysis, the cathode supplies electrons to metal ions for their reduction to the metal.
Feb 26, 2015 electrons flow through the external circuit from the anode of a reducing agent to the oxidising agent in the cathode.
In order to consume current stockpiles, ceramic uranium dioxide spent nuclear fuel will be subjected to an electrolytic reduction process. The current reduction process employs a platinum anode and a stainless steel alloy 316 cathode in a molten salt bath consisting of licl-2wt% li2o and occurs at 700⁰c.

The electrochemical reduction of carbon dioxide is the conversion of carbon dioxide to more reduced chemical species using electrical energy. It is one possible step in the broad scheme of carbon capture and utilization.
Dec 20, 2014 recovery of metallic uranium has been achieved by electrolytic reduction of uranium oxide in a molten licl–li2o electrolyte at 650 °c, foll.
The conservation of iron is used to exemplify electrolytic cleaning of metal artifacts. However, many of the conservation procedures for iron are applicable to other.
Meanwhile, electrolytic reductions of various kinds of solid ox-ides in cacl 2 and/or cacl 2-based molten salts have been investi-gated by many researchers in the last two decades. Reported the direct electrolytic reduction of tio 2 pellets in a cacl 2-based melt, known as the ffc cambridge process.

Best answer (a) in the electrolytic reduction of alumina, the graphite (anode) is oxidized by oxygen to co and further forms co2, so it is consumed and has to be replaced from time to time.
In a chemical reduction, the compound, generally, oxide of the metal is treated with a reducing agent, such as coke or carbon monoxide.

Aluminum metal is conventionally produced by the electrolytic reduction of al 2 o 3 in high-temperature fluoride-based molten salts, which is known as the hall–héroult process. The aluminum industry has remarkably advanced since the invention of this process in 1886. However, this process still consumes a large amount of electric power.
It is possible to construct a cell that does work on a chemical system by driving an electric current through the system. Electrolytic cells, like galvanic cells, are composed of two half-cells--one is a reduction half-cell, the other is an oxidation half-cell.
It is also possible to construct a cell that does work on a chemical system by driving an electric current through the system. Electrolysis is used to drive an oxidation-reduction reaction in a direction in which it does not occur spontaneously.
Electrolytic refining is a much more common process than electro winning, and such plants exist on a scale ranging from 1000 to 100,000 tons per year throughout the world. These are typically part of a larger project to extract raw metals from both waste and main ores and retrieve them.
