Questions & Step-by-Step Solutions

What is the main product of the electrolysis of water?
Correct Answer: Hydrogen gas (H2) and oxygen gas (O2)
  • Step 1: Understand that electrolysis is a process that uses electricity to break down a substance.
  • Step 2: Know that water (H2O) is made up of hydrogen and oxygen.
  • Step 3: When electricity is passed through water, it separates the water into its two components.
  • Step 4: The result of this separation is hydrogen gas (H2) and oxygen gas (O2).
  • Step 5: Therefore, the main products of the electrolysis of water are hydrogen gas and oxygen gas.
