What is As2Se5? Important knowledge about As2Se5.

1. Definition of As₂Se₅

As₂Se₅, also known as Arsenic Pentaselenide. In English, As₂Se₅ is also referred to as Arsenic Pentaselenide. It has a molar mass of 593.60 g/mol. The atomic mass of As₂Se₅ is determined through the total mass of the atoms in a molecule of As₂Se₅. The As₂Se₅ molecule consists of 2 As (Arsenic) atoms and 5 Se (Selenium) atoms. It also involves the formation of As₃+ and Se₂- ions.

2. Properties of As₂Se₅

2.1 Physical properties of As₂Se₅: As₂Se₅ is solid, black, odorless, and its pH can’t be measured due to its solid state.

2.2 Chemical properties of As₂Se₅: As₂Se₅ is very easily oxidized in the air, forming As₂O₅ and SeO₂. It also reacts with sulfur to form As₂S₅.

3. Common chemical equations of As₂Se₅ are very few because this substance is not commonly used in practice.

4. Synthesis of As₂Se₅

4.1 Laboratory synthesis of As₂Se₅: As₂Se₅ can be synthesized from the reaction between arsenic and selenium at high temperatures.

4.2 Industrial synthesis of As₂Se₅: Currently, As₂Se₅ is not produced on an industrial scale due to its unclear application in the industry.

Note: As₂Se₅ is a very toxic substance and needs to be handled with care.
