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.
The octanol-water partition coefficient, usually expressed as its logarithm (Log P), is a measure of differential solubility of a compound in a hydrophobic solvent and a hydrophilic solvent (water). The logarithm of these two values enables compounds to be ranked in terms of hydrophilicity (or hydrophobicity).
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic . Organic compounds
In organic chemistry, phosphate or orthophosphate is an organophosphate, ... Most other phosphates are only slightly soluble or are insoluble in water. As a rule, the ...
If the solubility, S, of an organic compound is known or predicted in both water and 1-octanol, then log P can be estimated as [46] [59] = . There are a variety of approaches to predict solubilities, and so log S. [60] [61]
Solubility in pure water at 20−25 °C 2.5 g/100 ml 2.4 g/100 ml ... are a group of aromatic organic compounds. They are widely-occurring phenols ...
The compounds are almost insoluble in water, weak acids, and (NH 4) 2 S/(NH 4) 2 S 2 solution is the key for separation of lead from analytical groups I to III elements, tin, arsenic, and antimony. The compounds dissolve in nitric and hydrochloric acids, to give elemental sulfur and hydrogen sulfide, respectively. [7]
