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.
Salts form upon evaporation of their solutions. [9] Once the solution is supersaturated and the solid compound nucleates. [9] This process occurs widely in nature and is the means of formation of the evaporite minerals. [10] Insoluble salts can be precipitated by mixing two solutions, one with the cation and one with the anion in it.
In chemistry, a salt is a neutral compound composed of cations bound to anions. In general, these salts are ionic compounds which form crystals. They are often soluble in water, where the two ions separate. Salts typically have a high melting point, low hardness, and low compressibility.
These salts (mostly the (II) salts) are often blue to green in color, rather than the orange color copper is known for. Despite being considered a semi-noble metal , copper is one of the most common salt-forming transition metals , along with iron .
Sodium chloride (table salt, rock salt) – NaCl; Sodium chlorite – NaClO 2; Sodium hypochlorite – NaOCl; Sodium perchlorate – NaClO 4; Strontium chloride – SrCl 2; Sulfur dichloride – SCl 2; Sulfuryl chloride – SO 2 Cl 2; Tantalum(III) chloride – TaCl 3; Tantalum(IV) chloride – TaCl 4; Tantalum(V) chloride – TaCl 5; Tellurium ...
Solubility is a property of interest in many aspects of science, including but not limited to: environmental predictions, biochemistry, pharmacy, drug-design, agrochemical design, and protein ligand binding. Aqueous solubility is of fundamental interest owing to the vital biological and transportation functions played by water.
These may be metal salts containing chloride ion such as sodium chloride, or more covalent chlorides of metals or nonmetals such as titanium(IV) chloride or thionyl chloride. See also [ edit ]
