Ca2VO44H2O

Ca2VO44H2O, also known as calcium orthovanadate tetrahydrate, is an inorganic compound. It is a hydrated salt of calcium and orthovanadate. The chemical formula indicates that for every two calcium ions (Ca2+), there are four orthovanadate ions (VO43-) and a total of forty water molecules (H2O) within its crystal structure. This extensive hydration suggests it is a salt that readily incorporates water.

The synthesis of Ca2VO44H2O typically involves reactions in aqueous solutions. It can be prepared by reacting a soluble calcium salt, such as calcium chloride or calcium nitrate, with a soluble vanadate salt, like sodium orthovanadate. The conditions of precipitation, including pH and temperature, are crucial for obtaining the desired hydrate.

Properties of Ca2VO44H2O are largely dictated by its hydrated nature. It is likely to be a crystalline solid. Upon heating, it will undergo dehydration, releasing water molecules and potentially transforming into a less hydrated or anhydrous form of calcium vanadate. The stability of the tetrahydrate form is dependent on ambient humidity and temperature. Information regarding its specific physical properties such as solubility, melting point, and spectroscopic data would typically be found in specialized chemical literature and databases.
