Article first time published onWhat are the chemical properties of magnesium hydroxide?
Magnesium hydroxide has the chemical formula Mg(OH)2 and the molecular weight of 58.3197 g/mol. Its CAS number is 1309-42-8 and its density is 2.345 g/cm3. It decomposes when heated to 360 °C and forms the oxide, MgO. It is very slightly soluble in water at 0.00122 g/100 ml and has a solubility product of 5.61 × 10−12.
Does magnesium and magnesium oxide have the same chemical properties?
Magnesium is an element with a specific atomic number (12) and symbol (Mg). … On the other hand, magnesium oxide is a compound derived when magnesium combines with oxygen. It has its own chemical formula (MgO) which is formed due to an ionic bond. However, this bond can be broken by chemical decomposition.
