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.
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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Its formation explains why the solubility of iodine in water may be increased by the addition of potassium iodide solution: [11] I 2 + I − ⇌ I − 3 (K eq = ~700 at 20 °C) Many other polyiodides may be found when solutions containing iodine and iodide crystallise, such as I − 5, I − 9, I 2− 4, and I 2−

Hexane and other volatile hydrocarbons (petroleum ether) present an aspiration risk. [26] n-Hexane is sometimes used as a denaturant for alcohol, and as a cleaning agent in the textile, furniture, and leather industries. It is slowly being replaced with other solvents. [27] Like gasoline, hexane is highly volatile and is an explosion risk.
1-Iodohexane is a flammable, difficult to ignite, light-sensitive liquid that is practically insoluble in water. [6] Copper is usually added to the compound as a stabilizer. [ 7 ]
Solubility in water. 2.5 g/100 mL (0 °C) 8.98 g/100 mL (20 °C) ... It can also be prepared by adding iodine to a hot, concentrated solution of sodium hydroxide or ...
