Which are applications of electrolysis? Check all that apply.

the splitting of pure water into hydrogen and oxygen

the discharging of a battery to do work

the joining of aluminum and oxygen to become ore

the creation of a surface resistant to corrosion on metal surfaces

the use of tools to etch a permanent logo on materials

the oxidizing of the cathode during recharging

the preservation of artifacts like old coins

Respuesta :

Answer;

  • the splitting of pure water into hydrogen and oxygen
  • the creation of a surface resistant to corrosion on metal surfaces
  • the use of tools to etch a permanent logo on materials

Explanation;

Electrolysis is a process that involves forcing electricity through a liquid or solution called electrolyte to cause a reaction to occur.

Electrolysis has many applications and uses. These includes;

  • Anodization which is an electrolytic process that makes the surface of metals resistant to corrosion.
  • Production of oxygen for spacecraft and nuclear submarines.
  • Electroplating is used in layering metals to fortify them. Electroplating is used in many industries for functional or decorative purposes, as in vehicle bodies and nickel coins.
  • Production of hydrogen for fuel, using a cheap source of electrical energy.
  • Electrolytic Etching of metal surfaces like tools or knives with a permanent mark or logo.
  • Electrolysis is also used in the cleaning and preservation of old artifacts. Etc.

A,D,E,G are the correct answers.
