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 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.
Calcium chloride is a highly soluble calcium salt. Hexahydrate calcium chloride (CaCl 2 ·6H 2 O) has solubility in water of 811 g/L at 25 °C. [1] Calcium chloride when taken orally completely dissociates into calcium ions (Ca 2+) in the gastrointestinal tract, resulting in readily bioavailable calcium. The high concentration of calcium ions ...
When measuring water treated with water softeners, high levels of total dissolved solids do not correlate to hard water, as water softeners do not reduce TDS; rather, they replace magnesium and calcium ions, which cause hard water, with an equal charge of sodium or potassium ions, e.g. Ca 2+ ⇌ 2 Na +, leaving overall TDS unchanged [9] or even ...
Brine (or briny water) is a high-concentration solution of salt (typically sodium chloride or calcium chloride) in water.In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).
Ammonium chloride precipitates and is removed by filtration, and the solution is recycled to produce more sodium carbonate. Hou's process eliminates the production of calcium chloride. The byproduct ammonium chloride can be refined, used as a fertilizer and may have greater commercial value than CaCl 2, thus reducing the extent of waste beds.
Calcium chloride is also used to reclaim alkali soils. CaCl 2 converts Na 2 CO 3 into NaCl precipitating CaCO 3. NaCl is drained off by leaching water. Calcium nitrate has a similar effect, with NaNO 3 in the leachate. Spent acid (HCl, H 2 SO 4, etc.) can also be used to reduce the excess Na 2 CO 3 in the soil/water.
Bittern (pl. bitterns), or nigari, is the salt solution formed when halite (table salt) precipitates from seawater or brines. Bitterns contain magnesium, calcium, and potassium ions as well as chloride, sulfate, iodide, and other ions. [2] [3] Bittern is commonly formed in salt ponds where the evaporation of water
