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.
At extremely low P CO 2, dissolved CO 2, bicarbonate ion, and carbonate ion largely evaporate from the solution, leaving a highly alkaline solution of calcium hydroxide, which is more soluble than CaCO 3. For P CO 2 = 10 −12 atm, the [Ca 2+][OH −] 2 product is still below the solubility product of Ca(OH) 2 (8 × 10 −6).
Calcium carbonate is more soluble at lower temperatures and at higher pressures. It is also more soluble if the concentration of dissolved CO 2 is higher. Adding a reactant to the above chemical equation pushes the equilibrium towards the right producing more products: Ca 2+ and HCO 3 − , and consuming more reactants CO 2 and calcium ...
Calcium, magnesium, and carbonate ions dissolve from rocks through which rainwater percolates before collection. Calcium salts, such as calcium carbonate [citation needed] and calcium bicarbonate (Ca(HCO 3) 2), are more soluble in hot water than cold water; thus, heating water does not cause calcium carbonate to precipitate per se.
As the groundwater enters the cave, the excess carbon dioxide is released from the solution of the bicarbonate, causing the much less soluble calcium carbonate to be deposited. In the reverse process, dissolved carbon dioxide (CO 2) in rainwater (H 2 O) reacts with limestone calcium carbonate (CaCO 3) to form soluble calcium bicarbonate (Ca(HCO ...
German investigators suspect a Berlin doctor of killing eight elderly patients under his care and setting fire to some of their homes to cover up his crimes, prosecutors said Thursday.
Aragonite is a carbonate mineral and one of the three most common naturally occurring crystal forms of calcium carbonate (Ca CO 3), the others being calcite and vaterite.It is formed by biological and physical processes, including precipitation from marine and freshwater environments.
