Physical properties of compounds
Solubility is a physical property of compounds. Some solvents selected under each category and their solubility in the solvent can be used as reference for refining or preparing solutions. (From Pharmacopoeia 2015)
Soluble: more than 10g/100g water (10 g of gas dissolved in 100 g of water) Soluble: more than 1 g/100 g of water, less than 10 g/100 g of water. Slightly soluble: more than 0.01 g/100 g of water, less than 1 g/100 g of water. Insoluble: more than 0 g/100 g of water, less than 0.01 g/100 g of water
Unless otherwise specified, weigh the test sample ground into fine powder or measure the liquid test sample, place it in a certain volume of solvent at 25 ℃ ± 2 ℃, and shake it vigorously for 30 seconds every 5 minutes; Observe the dissolution within 30 minutes. If there is no visible solute particle or liquid drop, it is deemed to be completely dissolved.

- Definition
- At room temperature (20 ℃), the solubility of a substance is more than 10g, which can generally be called soluble substance
At room temperature (20 ℃) Some material solubility Above 10g, it can be generally called Soluble Substance.
