FAQs
What is Hydrogen Peroxide Solution, 3%?
Hydrogen Peroxide Solution at 3 % concentration (H₂O₂) is a clear, colorless laboratory reagent made by dissolving hydrogen peroxide in water. It’s widely used as a moderate oxidizing agent in lab procedures where a dilute peroxide solution is required. CAS number is 7722-84-1.
What laboratory applications does 3 % hydrogen peroxide have?
A 3 % solution is used in labs for vacuum filtration, oxidations, cleaning glassware, and sample preparation, where moderate oxidizing power is sufficient. It also serves as a disinfectant and sterilizing reagent to remove contaminants from liquid samples.
What are common scientific uses of hydrogen peroxide?
Hydrogen peroxide acts as an oxidizing agent and can be used in organic reactions, disinfectant steps, and analytical workflows. In microbiology, it’s used for tests such as catalase assays. It also helps in surface cleaning due to its ability to break down organic residues.
Why is the 3 % concentration convenient?
Many lab and education protocols specify 3 % H₂O₂ because it balances reactivity and safety, strong enough to oxidize or disinfect, yet dilute enough to handle with common PPE and general lab precautions.
How should Hydrogen Peroxide Solution, 3% be stored?
Store in a cool, well-ventilated area away from heat and sunlight to reduce decomposition. Keep the container closed when not in use, and bring the peroxide to room temperature before use if it has chilled.
