It is prepared from quick lime which is calcium oxide. Its solution in water is basic. Lime is calcium carbonate (skeletal material of corals, liam stone ect) lime water is calcium carbonate dissiolved in water. When quick lime is added to water, the following reaction takes place. When quick lime reacts with water it forms slaked lime. At a temperature of 20 degrees Celsius, the solubility of slaked lime in water is roughly equal to 1.73 grams per litre. When quick lime ( CaO )reacts with water then lime water is produced. Slaked lime is also known as calcium hydroxide. CaO + H2O — Ca(OH)2 + heat mash up the seashells or other lime product into a powder heat it on a stove (boiling it ) it should look acidy(i haven't done this before) and then, add in water let it react and slaked lime!!! Note:seashells are calcium carbomate CACO3 and the quick lime is CAO and finally slaked lime CA(OH)2(aq) Slaked lime is also called pickling lime as it is used for making pickles and hydrated lime. At temperatures close to 853 Kelvin (which lies in the range of its melting point), slaked lime is known to lose water and begin undergoing a … Its chemical formula is C a (O H) 2 Ca{\left( {OH} \right)_2} C a (O H) 2 . Many confuse slaked lime with quick lime, slaked lime is calcium hydroxide and quick lime is calcium oxide and both are known by the same common name as lime. Slaked lime is not very soluble in water. CaO+H2O-----> Ca(OH) 2 It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or "slaked" with water. It is a white powder or a colorless crystal. Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2. Here,CaO is quick lime and Ca(OH)2 is slaked lime. CaO +H2O→Ca(OH)2 Here the product is Ca(OH)2 ,which is slaked lime or lime water. The formula for slaked lime is Ca(OH)2.
