Hydrogen gas




● Properties and characteristics


- The lightest of all gases, hydrogen is colorless, tasteless and odorless. The particle size of hydrogen is also smallest among gases. Hydrogen compounds formed when hydrogen combines with other elements are the most commonly existing compounds in the world. Hydrogen gas is flammable with a large explosion range, and also has excellent diffusivity and reducibility to saturate the unsaturated linkage parts of organic compounds. Such characteristics of hydrogen are widely used in fields such as electronics, chemicals, metals, glass, foods, oil and fat.
