Definition
This section has been translated automatically.

Solvents are generally organic or inorganic liquids (rarely also solids), which are able to dissolve or dilute substances without causing chemical reactions between the dissolved substance and the dissolving substance.

Dissolved are gases, liquids or solids. Not every solvent can dissolve every substance.

Preferably, liquids such as water or liquid organic solvents (alcohols, ethers, acetone, oils, etc.) are used to dissolve other substances. Individual solids can also dissolve other substances.
