What is SnH2? Important knowledge about SnH2.

1. Definition of SnH₂

SnH₂, also known as stannous hydride, is a chemical compound formed from stannum (Sn) and hydrogen (H) atoms. In English, it is known as stannane. It has a molar mass of 122.71 g/mol. The atomic mass of each element in the molecule is: Sn=118.71 and H=1, therefore, the molar mass of SnH₂ is 122.71 g/mol. In the SnH₂ molecule, one Sn atom combines with two H atoms to form a covalent bond.

2. Properties of SnH₂

2.1 Physical properties of SnH₂
SnH₂ is a solid, colorless, odorless substance without a specific pH level.

2.2 Chemical properties of SnH₂
SnH₂ is reactive, readily reacting with oxygen and water.

3. Common chemical equations involving SnH₂
   Given that SnH₂ readily reacts with oxygen and water, the following chemical equations can be observed:
   SnH₂ + O₂ -> SnO₂ + H₂O
   SnH₂ + 2H₂O -> Sn(OH)₂ + 2H₂

4. Synthesis of SnH₂

4.1 Laboratory synthesis of SnH₂
SnH₂ can be synthesized through the reaction of Sn and H₂ at high temperatures:
Sn + H₂ -> SnH₂

4.2 Industrial synthesis of SnH₂
On an industrial scale, SnH₂ is typically produced through the reduction of SnO₂ by H₂ at high temperatures.
