A volume of 600 m 3 (160,000 US gal) of seawater gives about 1 tonne (2,200 lb) of Mg(OH) 2. Ca(OH) 2 (K sp = 5.02 × 10 −6) [6] is far more soluble than Mg(OH) 2 (K sp = 5.61 × 10 −12) and drastically increases the pH value of seawater from 8.2 to 12.5. The less soluble Mg(OH) 2 precipitates because of the common ion effect due to the OH −
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 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:
Missouri carried out its fourth execution this year on Tuesday night. The man condemned to death was convicted in a 9-year-old girl's 2007 murder.
Carbonatation is a slow process that occurs in concrete where lime (CaO, or Ca(OH) 2 ) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium carbonate. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5.
