Calcium hydroxide (slaked lime)
Calcium hydroxide is a white, amorphous, corrosive powder that dissolves poorly in water (approx. 1.3 g/l at 20 °C). Lime water is the name given to the filtered aqueous solution, which reacts very strongly alkaline. It can be used as a detection reagent for carbon dioxide - pay someone to do my homework , since when air containing carbon dioxide is passed through it, sparingly soluble calcium carbonate precipitates in the form of tiny crystals.
Ca(OH)2 + CO2 → CaCO3 + H2O
Calcium hydroxide is produced by reacting calcium oxide (quicklime) with water. This reaction is called lime slaking.
The range of applications of the cheap base calcium hydroxide is extremely diverse and has been known for a long time. The Romans already used the suspension of calcium hydroxide - pay someone to do my online class - in lime water (milk of lime) to whiten walls.
The best known is the production of lime mortar; air is forced through a slurry of calcium hydroxide dissolved in water and three parts sand. The carbon dioxide in the air forms the hard, crystalline lime, CaCO3 - chemistry problem solver . Calcium hydroxide is also used technically for flue gas desulphurisation in power plants, as a binder for water-soluble paints, in the extraction of sugar from sugar beet and as an additive for fertilisers.
