Solubility

Solubility is generally understood to be the maximum amount of a substance that can be absorbed by a solvent at a certain temperature. The solubility of a substance may depend on the presence of other substances.

• A number of volume fractions of solvent <1 for one mass of substance is considered to be very easily soluble.
• A number of volume fractions of solvent of >1-<10 for one mass of substance is considered easily soluble.
• Soluble is defined as a number of parts by volume of solvent >10 - <30 for one mass of substance.
• A number of volume fractions of solvent of >30 - <100 for a mass of substance is considered to be slightly soluble.
• A number of volume fractions of solvent of >100 - <1000 for one mass of substance is considered to be poorly soluble.
• A number of volume fractions of solvent of >1000 - <10,000 for a mass of substance is considered very slightly soluble.
• A number of volume fractions of solvent of >10,000 for a mass of substance is considered insoluble.
