The tables 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. The substances are listed in alphabetical order.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Complete solubility occurs when the solvent and solute have the same valency. [2] A metal is more likely to dissolve a metal of higher valency, than vice versa. [1] [3] [4] The solute and solvent should have similar electronegativity.
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.

Juan Soto watches his solo home run in Game 2 of the 2024 World Series at Dodger Stadium. He hit .327 this past postseason for the Yankees with four homers, nine RBI and a 1.102 OPS in 14 games.
All data as presented in these tables is for materials in their standard state, which is at 25 °C and 100 kPa by definition. If values are given for other conditions, this is explicitly indicated. If values are given for other conditions, this is explicitly indicated.
