Question

What is the advantage of simple electrolysis

Answer 1

$\huge\mathfrak{Hello}$

• Electrolysis is cheaper compared to other methods and generally the results are permanent.
• The solution used which is made up of electrolysis keeps the metal free from corrosion or rusting.
• Electrolysis makes the metal attractive and gives an expensive appearance.
• Many of the substances which are useful are prepared from electrolysis process.
• Chlorine can be prepared by electrolysis of a solution of common salt.
• Hydrogen is also prepared by electrolysis of water.
• Heavy water for example Deuterium oxide which is used in nuclear reactor is also prepared from electrolysis of water.

Answer 2

Electrolysis is a technique that uses direct current (DC) power to power chemical reactions that are not otherwise spontaneous.

Cations are reduced at the cathode and anions are oxidized at the anode.

Explanation:

Advantages of electrolysis:

• Electrolysis is used to permanently remove facial hair from the body.  
• This electrolysis is an effective way to remove hair compared to creams, ointments, waxes, and medicines.
• Electrolysis is cheaper than other methods and the results are generally permanent.
• The electrolyte used protects the metal from corrosion and rust.
• Electrolysis makes metals attractive and gives them an expensive look.
• Many of the useful substances are produced by the electrolysis process.
•  Chlorine can be produced by electrolyzing a solution of  salt.  Hydrogen is also produced by the electrolysis of water.
• Heavy water such as deuterium oxide used in nuclear reactors is also produced by electrolysis of water.
• Electrolysis is a safe and effective way to remove hair.
• Electrolysis of a metal solution yields pure metal.  Impurities from the metal are removed by electrolysis.  
• Some  metals such as silver, copper, lead, zinc and nickel are refined or refined by an electrolytic refining process
