Oxygen Gas and Electrolytes Concepts

The video explores whether O2, or oxygen gas, is an electrolyte or non-electrolyte. It explains that electrolytes dissolve in water to produce ions, allowing the solution to conduct electricity. Although oxygen can dissolve in water, it does not dissociate into ions, making it a non-electrolyte. Therefore, O2 cannot conduct electricity in solution. Dr. B concludes that O2 is a non-electrolyte.

What is an electrolyte?

• A metal that dissolves in non-polar solvents.

• A gas that cannot conduct electricity.

• A substance that does not dissolve in water.

• A substance that dissolves in water and produces ions.

Why is oxygen gas considered a non-electrolyte?

• It is a metal that conducts electricity.

• It dissolves in water and produces ions.

• It dissolves in water but does not produce ions.

• It does not dissolve in water.

How do fish obtain oxygen from water?

• By breaking down water molecules.

• Through the dissolved oxygen in water.

• Through the dissolved ions in water.

• By absorbing water directly.

What happens to oxygen gas when it dissolves in water?

• It forms a solid precipitate.

• It reacts with water to form a new compound.

• It breaks apart into ions.

• It remains as dissolved gas without ionizing.

What is the main reason oxygen gas cannot conduct electricity?

• It forms a non-conductive compound.

• It is a metal.

• It does not dissolve in water.

• It does not dissociate into ions.

What is the final conclusion about oxygen gas in the video?

• Oxygen gas is an electrolyte.

• Oxygen gas is a non-electrolyte.

• Oxygen gas forms ions in water.

• Oxygen gas is a metal.
