Hydrogen dioxide corrosivity: Which statement about hydrogen dioxide is true?

• A. Not corrosive
• B. Highly corrosive and a strong oxidizing agent
• C. It is safe to mix with cleaners
• D. It does not react with water

Answer: (B)

Hydrogen peroxide is a powerful oxidizer and can be corrosive to skin, eyes, and metals, especially at higher concentrations. This is why the true statement identifies it as highly corrosive and a strong oxidizing agent. Its ability to donate oxygen makes it capable of causing chemical burns and material damage, which is why it must be handled with care and appropriate protective equipment. It mixes with water readily, forming an aqueous solution, so saying it doesn’t react with water isn’t correct. It also isn’t safe to mix hydrogen peroxide with many cleaners or chemicals, since such combinations can produce hazardous reactions or releases of oxygen gas. So the accurate takeaway is that hydrogen peroxide is a strong oxidizer and corrosive, not a non corrosive substance, not safe to mix with cleaners, and not something that simply “does not react with water.”
