Social Sciences. Share this Article:. Help me I really need help for my class work. ScienceAid welcomes all comments. Some packaging like foil and cans are also made from aluminum. Would you like to give back to the community by fixing a spelling mistake? Because it's reasonably strong, but not too heavy, your aluminum bicycle won't break and won't be too difficult to ride. It is mostly used in an alloy with another metal, this means it is mixed with another metal to produce another compound that has a certain desirable characteristic - like stainless steel.
The Extraction of Aluminium by Electrolysis including Ionic Equations. Aluminium oxide (Al2O3) is an ionic compound. When it is melted the Al3+ and O2- ions.
The steel container is coated with carbon (graphite) and this is the negative electrode (cathode).
Electrolysis of the alumina/cryolite solution gives aluminium at. Edited by Jamie (ScienceAid Editor), Taylor (ScienceAid Editor), SmartyPants, Aluminum is extracted from aluminum oxide by a process called electrolysis.
This means the anodes must be frequently replaced. Yes No I need help Uses Aluminum is the most widely used metal after iron.

The Process. Earth Sciences.
During electrolysis of aluminium oxide the product at the cathode undergoes: a)reduction b)oxidation c)both (a) and (b) d)no reaction takes place please give. Oxidation: the loss of electrons or the gain of oxygen. Reduction: the gain of electrons or the loss of oxygen.
Example: The electrolysis of lead.

Questions and Answers. The oxygen is attracted to the anode, and bubbles through the solution. Cryolite is a form of an aluminum compound that has a lower melting point that aluminum oxide.

For agglomerated alumina powder which is moved by the bath the rate control of the the Dissolution of Primary and Secondary Alumina Powders in Electrolysis", Light Metals– Mass Transfer and Time of Dissolution Equations concerning forced convection From Light MetalsLarry G.
In chemistry and manufacturing, electrolysis is a technique that uses a direct electric current Nevertheless, electrolysis, as a tool to study chemical reactions and obtain pure elements, Electrodes of metal, graphite and semiconductor material are widely used.
Oxidation of ions or neutral molecules occurs at the anode.
Therefore, aluminum is much more expensive than other metals that are easier to extract like ironbut its desirable characteristics mean that it is still widely used.

Aluminum has a very high melting point and strong bonding between atoms, so it doesn't readily dissolve in water. Some packaging like foil and cans are also made from aluminum.
