Hydrogen Peroxide Soln. 3% w/v Manufacturer,Supplier and Exporter in India

Hydrogen Peroxide Soln. 3% w/v (Product Code: SCL-979/232) is a dilute aqueous hydrogen peroxide solution used to generate oxygen, show catalysis and carry out oxidation tests in school and college laboratories. At 3% w/v strength and in a 500 ml analytical reagent pack with MSDS, it suits student chemistry demonstrations and catalase experiments in biology alike. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

What Is 3% Hydrogen Peroxide Solution Used For?

The classic demonstration adds a small amount of manganese dioxide to the solution in a flask fitted with a delivery tube; the peroxide decomposes steadily, and the oxygen is collected over water in a gas jar using standard gas collection apparatus, then identified by relighting a glowing splint. Comparing the rate with and without the catalyst, or with different catalysts, turns the same set-up into a lesson on reaction rates.

Biology classes drop small pieces of fresh liver or potato into the solution to show catalase at work: vigorous frothing appears with fresh tissue but not with boiled tissue, illustrating enzyme denaturation. In analysis, the solution oxidises iodide in acid to iodine and iron(II) to iron(III). Hydrogen peroxide slowly decomposes, faster in light, heat or contact with metals, so store it closed in a cool, dark place, never pour unused portions back into the bottle, and wear eye protection even at this dilution.

Frequently Asked Questions

What does 3% w/v mean for Hydrogen Peroxide Soln. 3% w/v?
It means 3 g of hydrogen peroxide is dissolved in every hundred millilitres of solution. This dilute strength of Hydrogen Peroxide Soln. 3% w/v is chosen for classroom work because it releases oxygen at a steady, manageable rate with a catalyst.

Is 3% Hydrogen Peroxide strong enough to relight a glowing splint?
Yes. With manganese dioxide as catalyst, 3% hydrogen peroxide gives a steady stream of oxygen that can be collected over water in a gas jar and identified by relighting a glowing splint, the standard school test for the gas.

Why does Hydrogen Peroxide solution lose strength after opening?
Hydrogen peroxide naturally decomposes to water and oxygen, and light, warmth, dust and metal contamination speed this up. Keep the bottle capped in a cool, dark cupboard, never return unused solution to it, and check activity before an important demonstration.

What is the shelf life of Hydrogen Peroxide Soln. 3% w/v?
No fixed period is given, because shelf life depends on the chemical, its grade and storage conditions, and peroxide solutions are especially sensitive to heat and light. Ask us for the expiry date of the batch of Hydrogen Peroxide Soln. 3% w/v you are quoted.

Is 3% Hydrogen Peroxide safe for students to handle?
It is far milder than concentrated grades, but 3% hydrogen peroxide can still irritate eyes and skin. Students should wear goggles, avoid swallowing it and follow the MSDS supplied with each 500 ml pack for first aid, spills and disposal.

Who supplies Hydrogen Peroxide Soln. 3% w/v?
Hydrogen Peroxide Soln. 3% w/v is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India, in 500 ml analytical reagent packs with an MSDS, for schools, colleges and distributors in India and international markets.

Can biology departments use Hydrogen Peroxide for catalase experiments?
Yes. The 3% hydrogen peroxide solution works well for comparing the frothing of fresh and boiled liver or potato tissue and for testing how temperature affects catalase activity in school and college biology practicals.
