What is SeH4? Important knowledge about SeH4

1. Definition of SeH₄

SeH₄, also known as Selenium Hydride, is a chemical substance with the model formula SeH₄. In English, it is called Selenium Hydride. This substance has an atomic mass of 81 and an atomic volume of 4. In a SeH₄ molecule, there is one Selenium (Se) atom connected to four Hydrogen (H) atoms. The ions of SeH₄ do not exist because SeH₄ is an organic substance that does not contain ions.

2. Properties of SeH₄

SeH₄ is a gas, colorless, with a pungent smell. The pH of SeH₄ cannot be determined because it is a gas. The chemical properties of SeH₄ are quite special, it can react with oxygen to form Selenium dioxide and water.

3. Common chemical equations of SeH₄

Below are some common chemical equations of SeH₄:

• Metal Reaction: SeH₄ does not react with metals.
• Acid Reaction: SeH₄ does not react with acids.
• Nonmetal Reaction: SeH₄ can react with O₂ to form SeO₂ and H₂O.
• Reaction with salts: SeH₄ does not react with salts.

4. Preparation of SeH₄

SeH₄ can be prepared through the process of preparing biological samples by reducing Selenium with Hydrogen. However, it should be noted that SeH₄ is a very toxic and dangerous substance, so the preparation should be conducted under the supervision of an expert. In the industry, SeH₄ is usually produced by the method of gas separation from the surrounding environment.
