∙ 13y agothe impure copper is used as the anode, the pure copper is the cathode. There is usually copper sulphate or a copper salt in solution as the electrolyte. Copper ions are reduced (gain electrons) at the cathode, and copper is oxidised (loses electrons) at anode.

∙ 13y agoActually, the impurities with metals are other salts and they are made from different anions and cations .
When they undergo electrolysis, the metals and other radicals are separated with one
radical going at one electrode and the other radical going to other.
This makes the metal get separated from the impurities and we get the metal.

The process of electrolysis used to coat objects with metals is?
galvanisation
The process of electrolysis used to coat objects with metals is called?
electroplating
Why is electrolysis used to extract certain metals?
Electrolysis can be used for the following purposes:Electroplating a baser metal with a more attractive metal. e.g. electroplating brass with goldRefining of impure metals. e.g. to remove impurities from copperElectrometallurgy - to extract metals from their compounds
What are the different applications of electrolysis?
1. electroplating 2. extraction of metals from ores 3. electrolytic refining 4.electrolysis can also be used for coating artificial jewelery with gold to give it an attractive look . 5.electrolysis can also be used for coating cutlery made up of cheap metal with silver to give it an attractive look .
What is used for purification of metal for casting?
The use of a flux to purify metals is a simple, brute force chemical separation hence it helps in the casting process.
What method is used to purify copper once extracte from its ore?

How do you Purify the yogurt using electrolysis method?
use a spoon.
What is the name of the process that uses electrodes to purify copper?
Electrolysis
What are some interesting uses of the science of electrolysis?
The science of electrolysis is used in the production of aluminum, potassium, chlorine, and magnesium. Electrolysis is also used in anodization, a process which makes the surface of metals resistant to corrosion.
Why is it important to recycle the metals you extract using electrolysis?
It takes a lot of electric power to refine metals by electrolysis. Such metals therefore are a kind of stored energy. If they are not recycled, that energy is lost.
Why is it important to recycle metals that you extract by electrolysis?
It takes a lot of electric power to refine metals by electrolysis. Such metals therefore are a kind of stored energy. If they are not recycled, that energy is lost, and more energy will be needed to refine more metals by electrolysis to replace them. High energy consumption is a major factor in environmental pollution.
How will you determine the purity of some metals?
use electrolysis
How many ways of making metals?
by electrolysis by thermal reduction
Name the metals extracted by electrolysis?
aluminium bromide lead
