give a brief account on the application of electrolysis

Kirti Gogia · Accepted Answer

Electrolysis is used for the following
purposes:

Electroplating
Electro-refining
Extraction of metals by electrolysis

1) Electroplating
The process of depositing a thin and compact layer of
superior metal over the inferior metal by the process of
electrolysis is called electroplating It can be of
many types such as silver plating and nickel plating It is done for
the following reasons:

To prevent metallic articles from rusting For example,
articles made of iron are electroplated with nickel so as to
prevent them from rusting
To improve appearance of articles For example, decoration
articles made from copper or brass are electroplated with silver to
improve their appearance

2)
Electro-refining
Electro-refining is the process by which impurities are removed
from an impure metal Metals such as silver and copper are
refined using electro-refining
3)
Electro-metallurgy
It refers to the process of extraction of metals from
their fused ores by the process of electrolysis
Example- Potassium and sodium can be extracted from their
fused ores using electro-metallurgy
