Answer 2

Answer:

INTRODUCTION:

In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential. The word "lysis" means to separate or break, so in terms, electrolysis would mean "breakdown via electricity".

PROCEDURE/PROCESS/WORKING:

Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. ... For electrolysis to work, the compound must contain ions. Covalent compounds cannot act as electrolytes because they contain neutral atoms .

USES:

• Electrolysis is used in the extraction of metals from their ores.
• It is used for refining certain metals such as copper and zinc.
• Electrolysis is used for the manufacture of chlorine.
• Electrolysis is used for electroplating many things we use every day.

ADVANTAGES:

• 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.

DISADVANTAGES:

• Disadvantages of electrolysis of water: it takes a lot of energy to separate the water into hydrogen and oxygen. If you burn fossil fuels to create the energy for electrolysis water the process produce lots of emission. of CO2.
• It takes a lot of electricity and that makes it expensive. Hence, electrolysis is only used for the most reactive metals. The method of extracting metal from its ore depends upon how reactive the metal is. The more ractive the metal, the more difficult and expensive it is to seperate from its ore.
