Simple Gas Set

Simple Gas preparation set. Including test tube, one hole stopper and acrylic tube for basic preparation of gas in a classroom. It is utilised when preparing a gas as the result of a chemical reaction. The gas can be examined in order to be identified the gas.

The decomposition of hydrogen peroxide (H₂O₂) is a chemical reaction where hydrogen peroxide breaks down into water and oxygen. This reaction can be significantly accelerated by the presence of a catalyst. Common catalysts include manganese dioxide (MnO2), yeast, and potassium iodide (KI). The reaction is often demonstrated with "elephant's toothpaste", where a large volume of oxygen is produced, creating a foam. 

How is H2 prepared?

Hydrogen gas (H₂) can be produced in the lab by reacting zinc granules with dilute hydrochloric or sulfuric acid. Industrially, hydrogen is primarily produced through steam reforming of hydrocarbons and electrolysis of water
