Hydrogen Detector

Hydrogen, the first element of the periodic table, is a colorless, odorless and tasteless, formed by diatomic molecules, under normal conditions. The hydrogen atom is formed by a core unit of positive charge and one electron. This is one of the main compounds of water and all organic matter, and it is widespread not only in land but in the entire Universe. There are three isotopes of hydrogen: protium, mass 1, in more than 99,985% of the natural element, deuterium, mass 2, found in the wild in about 0.015%, and tritium, mass 3, that appears in small amounts in nature but can be artificially produced by various nuclear reactions.

The hydrogen form 0.15% of the earth's crust and is the main constituent of water. 0.5 ppm H2 Hydrogen and variable proportions as water vapor are present in the atmosphere. Hydrogen is also an important component of biomass, constituting 14% by weight. Hydrogen occurs naturally in the atmosphere. The gas will be dissipated rapidly in well-ventilated areas. Any effect of hydrogen on plants or animals would be related to low oxygen environments. No adverse effect is expected to occur to plant life, except for frost produced in the presence of rapidly expanding gas. No evidence is currently available on the effect of hydrogen on aquatic life.

Hydrogen is the most flammable of all known substances. It is slightly soluble in organic solvents than in water. Many metals absorb hydrogen. The absorption of hydrogen by the steel may result in steel brittle, leading to defects in the chemical processing equipment. A normal temperature hydrogen is a substance which is not very reactive unless it was somehow activated, for example, by a suitable catalyst. At high temperature, it is very reactive. Although in general it is diatomic, molecular hydrogen dissociates into free atoms at high temperatures. Atomic hydrogen is a powerful reducing agent, even at room temperature. It reacts with the oxides and chlorides of many metals to produce metal-free. It reduces some salts to their metallic state and reacts with a number of elements, metals and nonmetals to produce their hydrides. Atomic hydrogen reacts with organic compounds to form a complex mixture of products. The heat released when hydrogen atoms recombine to form molecules of hydrogen is used to obtain high temperatures in atomic hydrogen welding.

The most important use of hydrogen is the synthesis of ammonia. The use of hydrogen is the rapid expansion in the refinement of fuel, such as decomposition of hydrogen (hydrocracking), and sulfur removal. Huge amounts of hydrogen are consumed in the catalytic hydrogenation of unsaturated vegetable oils for solid fat. Hydrogenation is used in the manufacture of organic chemicals. Huge amounts of hydrogen are used as rocket fuel, in combination with oxygen or flour, and as a rocket powered by nuclear energy. Hydrogen can be burned in internal combustion engines. Hydrogen fuel cells are being studied as a means of providing energy and research is conducted on hydrogen fuel as possible future great. For example, it can be converted and electricity from bio-fuels, and from natural gas and diesel fuel, theoretically with no emissions of CO2, or toxic chemicals.

Because hydrogen is extremely flammable, its many reactions may cause fire or explosion. As the gas mixes well with air, explosive mixtures are easily formed. In addition, the gas is lighter than air. The gas can be absorbed into the body by inhalation and in high concentrations can cause a low oxygen environment. Individuals breathing such an atmosphere may experience symptoms that include headaches, ringing in the ears, dizziness, drowsiness, unconsciousness, nausea, vom.
