Did you know?
Magnesium bromide is a chemical compound of magnesium and bromine, with the chemical formula MgBr2. It is white and deliquescent crystalline solid. It is often used as a mild sedative and as an anticonvulsant for treatment of nervous disorders. It is water-soluble and somewhat soluble in alcohol. It can be found … Visa mer Magnesium bromide can be synthesized by treating with magnesium oxide (and related basic salts) with hydrobromic acid. It can also be made by reacting magnesium carbonate and hydrobromic acids, and collecting … Visa mer Magnesium bromide is used as a Lewis acid catalyst in some organic synthesis, e.g., in aldol reaction. In organosilicon chemistry, magnesium bromide forms adducts R2SiXMgBr2. Magnesium bromide also has been used as a tranquilizer. Visa mer Webb3 juli 2024 · Examples of colligative properties include vapor pressure lowering, freezing point depression, osmotic pressure, and boiling point elevation. For example, adding a pinch of salt to a cup of water makes the water freeze at a lower temperature than it normally would, boil at a higher temperature, have a lower vapor pressure, and …
