Electrolytic flotation uses which gas mixture as a byproduct?

Electrolytic flotation uses which gas mixture as a byproduct?

• A. Hydrogen and oxygen
• B. Air
• C. Nitrogen
• D. Carbon dioxide

Answer: (A)

Electrolytic flotation relies on gas bubbles generated by electrolysis of water to lift contaminants. When an electric current passes through water, it splits into hydrogen gas at the cathode and oxygen gas at the anode, producing a hydrogen–oxygen mixture in a 2:1 ratio. These tiny bubbles attach to particles and carry them to the surface for removal. This gas mixture is produced in situ, not drawn from the air, so the byproduct is hydrogen and oxygen, not nitrogen or carbon dioxide.
