Can elements be separated from connections

Chemical methods of separation of compounds

In the field of material separation, there are two major separation processes, physical and chemical separation processes.
Physical separation methods are based on the different physical properties of batch constituents (solubility, boiling point) and thus mixtures / batches can be separated. Not to be confused with the term “physical separation methods” is the term “chemical separation methods”. In chemical separation processes, compounds are split into elements with the help of chemical properties (e.g. dissociation energy, normal potential) with the help of reactions.

In summary: The separation of substance mixtures / batches is based on the utilization of the different physical and chemical properties of the pure substances involved.

Significance of separation processes:

In nature, most substances exist as compounds, mixtures or blends. For applications, e.g. medical products, pure substances must be available. This is why processes for separating substances are extremely important. Chemical separation processes are presented below.

electrolysis:

Electrolysis is a process in which an electric current forces a redox reaction in an electrolyte solution, e.g. for the extraction of metals or the production of hydrogen. If there are several reducible cations in an electrolyte solution, the cations that have a more positive (weaker negative) potential in the electrochemical series are reduced first.

Example: 2H2O -> 2H2+ O2

Nuclear reactions:

A nuclear reaction is a process in which at least one nucleus is converted when an atomic nucleus collides with another nucleus or particle. Probably the best known nuclear reaction takes place in the core of the sun. There is a temperature of more than 15 million ° C and a pressure of around 300 billion bar. In the nuclear reaction, hydrogen atoms fuse to form a helium nucleus.
