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.
Crystal structure of calcite. Calcium carbonate is a chemical compound with the chemical formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls.
A few, such as calcium sulfate and cerium(III) sulfate, become less soluble in water as temperature increases (ΔH < 0). [15] This is also the case for calcium hydroxide (portlandite), whose solubility at 70 °C is about half of its value at 25 °C. The dissolution of calcium hydroxide in water is also an exothermic process (ΔH < 0).
Lead(II) sulfate: 7.96 (18 °C) Lithium carbonate: 2.77 Magnesium carbonate: 4.59 (12 °C) Magnesium fluoride: 8.19 (27 °C) Magnesium hydroxide: 10.92 (18 °C) Magnesium oxalate: 4.07 (18 °C) Manganese(II) hydroxide: 13.40 (18 °C) Mercury(I) bromide: 20.89 Mercury(I) chloride: 17.70 Mercury(I) iodide: 27.92 Potassium hydrogen tartrate: 3.42 ...
