Chemical Properties of Hydrogen

On the chemical properties of hydrogen
Hydrogen is light and pure. Its chemical properties are specific, and it shows its unique energy in various chemical reactions.

Hydrogen is flammable. When it encounters oxygen and is supplemented by a fire source, it will react violently and turn into water. This reaction has a light blue flame and a huge heat, which can be used for energy. Looking at it, the combustion formula is as follows: Dihydrogen and monooxygen are combined to obtain dihydrate molecules. That is, $2H_ {2} + O_ {2}\ stackrel {ignited }{=\!=\!=} {2} O $. In this reaction, hydrogen loses electrons, and oxygen gains electrons, forming a redox state. In addition, hydrogen is reducing. In the reaction of metal oxides, it is often used as a reducing agent. When hydrogen meets copper oxide, when heated, hydrogen grabs oxygen from copper oxide and precipitates copper. It becomes as follows: When hydrogen and copper oxide are heated, copper and water are obtained. That is, $H_ {2} + CuO\ stackrel {\ Delta }{=\!=\!=} Cu + H_ {2} O $. Here, hydrogen returns copper in copper oxide from the normal divalent state to the zero valence state, and itself is oxidized into water, demonstrating its reduction ability.

In addition, hydrogen and active metals can form hydrides. Active metals such as sodium, potassium, etc., interact with hydrogen, the metal loses electrons, and the hydrogen gains electrons, forming negative monovalent hydrogen ions, and then forming ionic hydrides. Such as sodium and hydrogen, heated and combined to obtain sodium hydride. That is, $2Na + H_ {2}\ stackrel {\ Delta }{=\!=\!=} 2Na H $. Among them, hydrogen is oxidized, and electrons are obtained to form negative hydrogen ions, which form ionic bonds with metal ions.

The chemical properties of hydrogen are of great significance in the fields of energy, metallurgy, and chemical industry. Its flammability provides energy, and its reductivity is used for metal refining. It has potential paths to form hydrides with metals and materials. The property of clear hydrogen can promote the progress of science and the innovation of technology.
