CAS 1333-74-0 Metallic Ores H2 Hydrogen Gas Reducing Agent High Purity

Description:

Hydrogen is a colorless and odorless gas. The molecular form is H2.

At standard temperature and pressure, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2. Hydrogen is the lightest element on the periodic table. Its monatomic form is the most abundant chemical substance in the Universe.

The most commonisotope of hydrogen, termed protium, has one proton and no neutrons. Since hydrogen readily forms covalent compounds with most non-metallic elements, most of the hydrogen on

Earth exists in molecular forms such as water or organic compounds. Hydrogen plays a particularly important role in acid–base reactionsbecause most acid-base reactions involve the exchange of protons between soluble molecules. In ionic compounds, hydrogen can take the form of a negative charge when it is known as ahydride, or as a positively charged species denoted by the symbol H+. The hydrogen cation is written as though composed of a bare proton, but in reality, hydrogen cations inionic compounds are always more complex. As the only neutral atom for which the Schrödinger equation can be solved analytically, study of the energetics and bonding of the hydrogen atom has played a key role in the development of quantum mechanics.

Compounds of hydrogen are often called hydrides, a term that is used fairly loosely. The term "hydride" suggests that the H atom has acquired a negative or anionic character, denoted H−, and is used when hydrogen forms a compound with a more electropositive element.

Hydrogen has three naturally occurring isotopes, denoted 1H, 2H and 3H. Other, highly unstable nuclei (4H to 7H) have been synthesized in the laboratory but not observed in nature.

Large quantities of H2 are needed in the petroleum and chemical industries. The largest application of H2 is for the processing of fossil fuels, and in the production of ammonia.
