What is SnCl4? Important knowledge about SnCl4.

1. Definition of SnCl₄

SnCl₄, also known as Tetrachlorostannate or Tetrachlorotin in English, is a chemical substance with a molecular mass of 260.52 g/mol. In the molecule of SnCl₄, there is one Stannum atom (Sn) and four Chlorine atoms (Cl). SnCl₄ is an ionic substance, in which the Sn₄+ ion forms an ionic bond with 4 Cl- ions.

2. Properties of SnCl₄

2.1 Physical properties of SnCl₄

SnCl₄ is a colorless liquid, has a characteristic odor, and is a strong acid with a low pH.

2.2 Chemical properties of SnCl₄

SnCl₄ is highly reactive with water, forming hydrochloric acid and stannic hydroxide. It can also react with metals like aluminium to form complex compounds.

3. Common chemical equations of SnCl₄

SnCl₄ can react with aluminum according to the equation:
2 Al + 3SnCl₄ -> 2AlCl₃ + 3Sn

SnCl₄ can also react with water to produce hydrochloric acid and stannic hydroxide:
SnCl₄ + 4H₂O -> H₄SnO₄ + 4HCl

4. Synthesis of SnCl₄

4.1 Laboratory synthesis of SnCl₄

In the lab environment, SnCl₄ is often synthesized by reacting hydrochloric acid with the Tin metal.

4.2 Industrial synthesis of SnCl₄

On an industrial scale, SnCl₄ is produced by reacting chlorine with stannum at high temperatures.
