It is a white crystalline solid, soluble in water but not in ethanol. Magnesium sulfate is usually encountered in the form of a hydrate MgSO 4 · n H 2 O , for various values of n between 1 and 11. The most common is the heptahydrate MgSO 4 ·7H 2 O , [ 1 ] known as Epsom salt , which is a household chemical with many traditional uses ...
The hexahydrate Mg(ClO 3) 2 ·6H 2 O decomposes to the tetrahydrate at 35 °C. At 65 °C, it dehydrates to the dihydrate, then at 80 °C forms a basic salt. If further heated to 120 °C it decomposes to water, oxygen, chlorine, and magnesium oxide. [2] As confirmed by X-ray crystallography, the di- and hexahydrates feature octahedral Mg 2 ...
Magnesium chloride is an inorganic compound with the formula Mg Cl 2.It forms hydrates MgCl 2 ·nH 2 O, where n can range from 1 to 12. These salts are colorless or white solids that are highly soluble in water.
This floc facilitates the separation of suspended materials, clarifying the water. [10] Iron(III) chloride is also used to remove soluble phosphate from wastewater. Iron(III) phosphate is insoluble and thus precipitates as a solid. [34] One potential advantage of its use in water treatment, is that the ferric ion oxidizes (deodorizes) hydrogen ...
Dysprosium(III) chloride (DyCl 3), also known as dysprosium trichloride, is a compound of dysprosium and chlorine.It is a white to yellow solid which rapidly absorbs water on exposure to moist air to form a hexahydrate, DyCl 3 ·6H 2 O. Simple rapid heating of the hydrate causes partial hydrolysis [2] to an oxychloride, DyOCl.
Since magnesium nitrate has a high affinity for water, heating the hexahydrate does not result in the dehydration of the salt, but rather its decomposition into magnesium oxide, oxygen, and nitrogen oxides: 2 Mg(NO 3) 2 → 2 MgO + 4 NO 2 + O 2. The absorption of these nitrogen oxides in water is one possible route to synthesize nitric acid.
Only four of the six water molecules in the formula is bound to the nickel, and the remaining two are water of crystallization, so the formula of nickel(II) chloride hexahydrate is [NiCl 2 (H 2 O) 4]·2H 2 O. [9] Cobalt(II) chloride hexahydrate has a similar structure. The hexahydrate occurs in nature as the very rare mineral nickelbischofite.
VCl 3 dissolves in water to give the aquo complexes. From these solutions, the hexahydrate [VCl 2 (H 2 O) 4]Cl. 2H 2 O crystallizes. In other words, two of the water molecules are not bound to the vanadium, whose structure resembles the corresponding Fe(III) derivative. Removal of the two bound chloride ligands gives the green hexaaquo complex ...
