The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
Water temperature can have a significant effect on the solubility of compounds. Refer to the chart below to find reference values per gram of common compounds and salts (with chemical formula) at six temperatures of 100 g of water from 0 degrees to 100 degrees Celsius.
Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts.
30 sty 2023 · A solution of a salt (orange and green ions) in water (blue molecules). The ions of the salt are completely distributed throughout the water. Pieces of salt are not visible in the solution; the salt particles are too small. The salt is separated into individual ions, surrounded by water molecules.
Learn the rules and exceptions for solubility of salts in water based on their chemical formulas and properties. See a table of common salts and their solubility categories.
Solubility of a substance is useful when separating mixtures. For example, a mixture of salt (sodium chloride) and silica may be separated by dissolving the salt in water, and filtering off the undissolved silica. The synthesis of chemical compounds, by the milligram in a laboratory, or by the ton in industry, both make use of the relative ...
