What is GeH4? Important knowledge about GeH4.

Definition of GeH₄:
1.1 The common name for GeH₄ is germane, also known as tetrahydridogermanium.
1.2 Its English name is also germane.
1.3 The atomic weight of GeH₄ is 76.63, consisting of one germanium (Ge) atom and four hydrogen (H) atoms.
1.4 The atomic mass of GeH₄ is 76.63.
1.5 The molecular structure of GeH₄ includes a central Ge atom surrounded by four H atoms, forming a tetrahedron.
1.6 GeH₄ does not form ions as it is not an ionic compound.

Properties of GeH₄:
2.1 The physical properties of GeH₄: It is a colorless, odorless gas at standard conditions and does not have a pH value as it is not a liquid or solution.
2.2 The chemical properties of GeH₄: It can participate in oxidation and reduction reactions, for example, reacting with oxygen to form germanium dioxide and water.

Common chemical equations involving GeH₄:
GeH₄ mainly participates in oxidation and reduction reactions. For example:
2 GeH₄ + O₂ -> 2GeO₂ + 4H₂O
Note that GeH₄ does not react with metals, acids, nonmetals, or salts.

Preparation of GeH₄:
4.1 The preparation of GeH₄ in the laboratory is usually done by reacting germanium with hydrochloric acid and using zinc for reduction.
Ge + 4HCl + Zn -> GeH₄ + ZnCl₂
4.2 On an industrial scale, GeH₄ is typically produced by reacting germanium with hydrofluoric acid and using sodium for reduction.
Ge + 4HF + Na -> GeH₄ + NaF
