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 ...
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.
The hexahydrate is most commonly encountered. It is a violet solid that dissolves in water to give air-sensitive solutions of the aquo complex. The salt is isomorphous with [Mg(H 2 O) 6]SO 4. Compared to the V–O bond length of 191 pm in [V(H 2 O) 6] 3+, the V–O distance is 212 pm in the [V(H 2 O) 6]SO 4. This nearly 10% elongation reflects ...
Yttrium(III) nitrate hexahydrate loses crystallized water at relatively low temperature. Upon further heating, basic salt YONO 3 is formed. [2] At 600 C, the thermal decomposition is complete. Y 2 O 3 is the final product. [3] Y(NO 3) 3 ·3TBP is formed when tributyl phosphate is used as the extracting solvent. [4]
Magnesium perchlorate is a white powder that is easily soluble in water, which can be obtained by the reaction of magnesium oxide and perchloric acid. The hexahydrate crystallizes from the solution, and then it is dried with phosphorus pentoxide in a vacuum at 200~250 °C to obtain the anhydrous form.
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.
Upon heating to 300 °C, it decomposes to sodium sulfate and sodium polysulfide: 4 Na 2 S 2 O 3 → 3 Na 2 SO 4 + Na 2 S 5. Thiosulfate salts characteristically decompose upon treatment with acids. Initial protonation occurs at sulfur. When the protonation is conducted in diethyl ether at −78 °C, H 2 S 2 O 3 (thiosulfuric acid) can be obtained.
Cerium nitrate hexahydrate, with the formula Ce(NO 3) 3.6H 2 O (CAS number 10294-41-4) is the most common nitrate of cerium(III). It is a component in a burn treatment cream that also includes silver sulphadiazine .
