Question

what is electrolysis ?give three uses?​

Answer 1

Answer:

here is your answer

Explanation:

Electrolysis is a chemical reaction for separating hydrogen and oxygen which are the components of water.

Uses:

1. Separation of hydrogen and oxygen from water.

2. It is used for the purification of metals from ores.

3. It is also used in electroplating.

Answer 2

Electrolysis:

• Electrolysis is a term that is loosely applied to the corrosion process. The term refers to solution phenomena and not to corrosion itself.

• Electrolysis is the degradation of an electrolyte that occurs as a result of passing electrical current through it.

• Electrolysis, is the process of deteriorating metal by a reaction process. Although the results are the same, corrosion and electrolysis differ by the time required for the process and causes of process.

The main components required to achieve electrolysis are:

• An electrolyte: a substance containing free ions.
• Direct current supply: provides the energy necessary to create or discharge the ions in the electrolytes.
• Two electrodes: an electrical conductor.

There are two option to protect material from electrolysis:

• Repeatedly replacing the sacrificial anode.
• Finding the source of the stray voltage and eliminating it.

• Corrosion and electrolysis can cause great damage to metals in a marine environment. The sacrificial anode will help to protect materials.
• However, it is impossible to protect against all forms of electrolysis, if the anode is not inspected regularly, protection will be compromised.
• Since damage can occur before an anode can be changed, it becomes costly to continually change the anode.

Uses of electrolysis:

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