Properties of Hydrogen Gas
Hydrogen is a colorless and odorless gas. Its density is the lightest, only one-fourteenth of that of air. It is insoluble in water. Under normal temperature, its properties are quite stable, but it will burn in case of fire. The flame is light blue and combines with oxygen to produce water, and its reaction is enthusiastic.
Hydrogen is flammable and is often used as a fuel. When burned, a lot of heat is released, and the product is only water, clean and environmentally friendly. It is also reductive. Under heating conditions, it can reduce metals in metal oxides. This property is widely used in metallurgy and other industries.
And hydrogen is produced by various methods, either by reacting active metals with acids, or by electrolyzing water. With its various characteristics, it has important applications in many fields, such as industry and scientific research.
