Calcium hydroxide is modestly soluble in water, as seen for many dihydroxides. Its solubility increases from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. [8] Its solubility product K sp of 5.02 × 10 −6 at 25 °C, [1] its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction:
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.
Brucite crystals (mineral form of Mg(OH) 2) from the Sverdlovsk Region, Urals, Russia (size: 10.5 cm × 7.8 cm × 7.4 cm or 4.1 in × 3.1 in × 2.9 in) Brucite , the mineral form of Mg(OH) 2 commonly found in nature also occurs in the 1:2:1 clay minerals amongst others, in chlorite , in which it occupies the interlayer position normally filled ...
Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. The quicklime neutralizes the acidic oxides, SiO 2, Al 2 O 3, and Fe 2 O 3, to produce a basic molten slag. [10] Ground quicklime is used in the production of aerated concrete such as blocks with densities of ca. 0.6–1.0 g/cm 3 (9.8–16.4 g/cu in). [10]

where the solubility product for [Ca 2+][CO 2− 3] is given as anywhere from K sp = 3.7 × 10 −9 to K sp = 8.7 × 10 −9 at 25 °C, depending upon the data source. [ 80 ] [ 81 ] What the equation means is that the product of molar concentration of calcium ions ( moles of dissolved Ca 2+ per liter of solution) with the molar concentration of ...
