This colorless salt is highly soluble in water and absorbs moisture from the atmosphere – a characteristic described as hygroscopic. Under standard conditions, it usually exists as a tetrahydrate form, represented as Ca(NO 3 ) 2 •4H 2 O.
Calcium nitrate are inorganic compounds with the formula Ca(NO 3) 2 (H 2 O) x. The anhydrous compound, which is rarely encountered, absorbs moisture from the air to give the tetrahydrate . Both anhydrous and hydrated forms are colourless salts .
Quick Reference. A white deliquescent compound, Ca (NO 3) 2, that is very soluble in water; cubic; r.d. 2.50; m.p. 561°C. It can be prepared by neutralizing nitric acid with calcium carbonate and crystallizing it from solution as the tetrahydrate Ca (NO 3) 2.4H 2 O, which exists in two monoclinic crystalline forms (α, r.d. 1.9; β, r.d. 1.82).
8 cze 2024 · Calcium nitrate, with the chemical formula Ca (NO3)2, is a salt composed of calcium and nitrate ions. It is a crystalline solid that is highly soluble in water, with a solubility of up to 121 grams per 100 milliliters of water at 20°C. When dissolved in water, calcium nitrate dissociates into calcium (Ca2+) and nitrate (NO3-) ions.
Abstract. In this page, the calcium nitrate salt is discussed. Its behavior regarding solubility and hygroscopicity will be reviewed as well as its different hydration states. Solubility. Figure 1: Solubility of calcium nitrate in water. The molality m [n (Ca (NO 3) 2 •xH 2 O)•kg (H 2 O) -1] is plotted against the temperature.
