Description
Hydrogen is colorless, odorless, tasteless, flammable, and nontoxic. It exists as a gas at ambient temperatures and atmospheric pressures. It is the lightest gas known, with a density approximately 0.07% that of air. Hydrogen is present in the atmosphere occurring in concentrations of only about 0.5 ppm by volume at lower altitudes.Related product price
