Sulfur hydride
Sulfur hydride, with the formula $H_2S $. This is colorless and smells like rotten eggs. Its properties are quite different, and it is involved in all kinds of things.
Looking at its physical properties, under normal temperature and pressure, $H_2S $is a gas, which is easily soluble in water, and dissolves into acid, which is called hydrosulfuric acid. Its smell is foul, and it is easy to feel discomfort when people smell it, and it is even harmful to health. And this gas is heavier than air and often gathers in low-lying places.
In terms of its chemical properties, $H_2S $is reductive. In case of strong oxidants, such as oxygen, it can react. When burned, the flame is light blue, and the product is sulfur dioxide and water; if there is insufficient oxygen, the sulfur-producing elemental substance and water. In solution, it can react with a variety of metal ions to produce insoluble sulfide precipitation. In case of copper ions, it is a black copper sulfide precipitation, which is a common means for qualitative detection of metal ions.
As for its use, although its taste is not good, it can also be used in industry. It can be used to prepare sulfur, which is an important raw material in the chemical industry, used for sulfuric acid, rubber vulcanization, etc. It is also used in metal smelting, with its reaction with metal ions to separate and purify metals.
However, $H_2S $is also harmful. In the environment, if too much is released, it can cause air pollution and damage the ecology. In the human body, excessive inhalation can paralyze the nerves, cause breathing difficulties, coma, and even endanger life. Therefore, when involving this substance, it is necessary to be cautious and take protective measures to prevent harm.
Cover sulfide $H_2S $, has unique properties, advantages and disadvantages, people should be well aware of it, use it, avoid its harm and pursue its benefits.
