Hydrazine

Hydrazine is an inorganic compound. It is mainly used as a foaming agent in preparing polymer foams, but significant applications also include its uses as a precursor to polymerization catalysts and pharmaceuticals. Additionally, hydrazine is used in various rocket fuels and to prepare the gas precursors used in air bags. It is used within both nuclear and conventional electrical power plant steam cycles to control concentrations of dissolved oxygen in an effort to reduce corrosion. The majority use of hydrazine is as a precursor to blowing agents. It is a useful building block in organic synthesis of pesticides. It is also used as a propellant on board space vehicles, and to both reduce the concentration of dissolved oxygen in and control pH of water used in large industrial boilers.

Hydrofluoric Acid

Hydrofluoric acid is a solution of hydrogen fluoride in water. It is a valued source of fluorine, being the precursor to numerous pharmaceuticals such as fluoxetine and diverse materials such as polytetrafluoroethylene. It is a highly corrosive acid, capable of dissolving many materials, especially oxides. The principal use of hydrofluoric acid is in organofluorine chemistry. Most high-volume inorganic fluoride compounds are prepared from hydrofluoric acid. The ability of hydrofluoric acid to dissolve metal oxides is the basis of several applications. It removes oxide impurities from stainless steel, a process called pickling, and silicon wafers in the semiconductor industry. In similar manner, it is also used to etch glass. A 5% to 9% hydrofluoric acid gel is also commonly used to etch all ceramic dental restorations to improve bonding. For similar reasons, dilute hydrofluoric acid is a component of household rust stain remover and in car washes in "wheel cleaner" compounds. Diluted hydrofluoric acid is used in the petroleum industry in a mixture with other acids in order to stimulate the production of water, oil, and gas wells specifically where sandstone is involved.

Hydrogen

Hydrogen is the lightest and most abundant chemical element.The most common isotope of hydrogen is protium with a single proton and no neutrons. In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by identifying the gas from a metal-acid reaction as "phlogiston", meaning "flammable air" and further finding in 1781 that the gas produces water when burned. He is usually given credit for its discovery as an element. In 1783, Antoine Lavoisier gave the element the name hydrogen when he and Laplace reproduced Cavendish's finding that water is produced when hydrogen is burned. Large quantities of hydrogen are needed in the petroleum and chemical industries. The largest application of hydrogen is for the processing of fossil fuels, and in the production of ammonia. It is used as a hydrogenating agent, particularly in increasing the level of saturation of unsaturated fats and oils, and in the production of methanol. It is similarly the source of hydrogen in the manufacture of hydrochloric acid. It is also used as a reducing agent of metallic ores. It is commonly used in power stations, as a coolant in generators, due to its specific heat capacity being considerably higher than any other gas.

Hydrogen Bromide

Hydrogen bromide is the diatomic molecule. It can be synthesized by a variety of methods. It may be prepared in the laboratory by distillation of a solution of sodium or potassium bromide with phosphoric acid or diluted sulfuric acid. It can also be found as a liquid, either as hydrobromic acid (hydrogen bromide dissolved in water) or as a compressed gas under pressure (anhydrous hydrogen bromide). Hydrogen bromide can react violently when mixed with some chemicals, metals or water, forming a flammable, explosive gas. Hydrogen bromide is used to make chemicals and drugs, as a solvent and as a veterinary drug, used in combination with hydrogen chloride and chlorine for plasma etching of polysilicon, used in the manufacture of organic and inorganic bromides and hydrobromic acid, as a reducing agent, and as a catalyst in controlled oxidations, used in the alkylation of aromatic compounds, and in the isomerization of conjugated diolefins.

Hydrogen Sulfide

Hydrogen sulfide is a very poisonous, flammable gas with the characteristic foul odor of rotten eggs. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers. It also occurs in volcanic gases, natural gas, and some well waters. The human body produces small amounts of H2S and uses it as a signaling molecule. Several organosulfur compounds are produced using hydrogen sulfide. Upon combining with alkali metal bases, hydrogen sulfide converts to alkali hydrosulfides such as sodium hydrosulfide and sodium sulfide, which are used in the degradation of biopolymers. Hydrogen sulfide used to have importance in analytical chemistry for well over a century, in the qualitative inorganic analysis of metal ions. In the purification of metal ores by flotation, mineral powders are often treated with hydrogen sulfide to enhance the separation.
