Magnesium perchlorate is a powerful oxidizing agent, with the formula Mg(ClO 4) 2. The salt is also a superior drying agent for gas analysis. Magnesium perchlorate decomposes at 250 °C. [2] The heat of formation is -568.90 kJ/mol. [3] The enthalpy of solution is quite high, so reactions are done in large amounts of water to dilute it.
Perfluorobutane can replace Halon 1301 in fire extinguishers, [4] as well as the gas component for newer generation microbubble ultrasound contrast agents.Sonazoid [5] is one such microbubble formulation developed by Amersham Health that uses perfluorobutane for the gas core.
Actovegin is a highly filtered extract obtained from calf blood which enhances aerobic oxidation in mammals. [1] This improves absorption of glucose and oxygen uptake in tissue, [1] which may enhance physical performance and stamina.
Treating the solution of different soluble magnesium salts with alkaline water induces the precipitation of the solid hydroxide Mg(OH) 2: Mg 2+ + 2 OH − → Mg(OH) 2. As Mg 2+ is the second most abundant cation present in seawater after Na +, it can be economically extracted directly from seawater by alkalinisation as described here above.
Magnesium glycinate has been studied with applicability to patients with a bowel resection [1] or pregnancy-induced leg cramps. [2] Less scientific research exists on magnesium glycinate in therapeutic applications than other more common forms of magnesium salt such as magnesium chloride, oxide or citrate.
2 CH 3 COOH + Mg(OH) 2 → (CH 3 COO) 2 Mg + 2 H 2 O. Magnesium carbonate suspended in distilled water with 20% acetic acid solution. [8] 2 CH 3 COOH + MgCO 3 → Mg(CH 3 COO) 2 + CO 2 + H 2 O. Reacting metallic magnesium with acetic acid dissolved in dry benzene causes magnesium acetate to form along with the release of hydrogen gas. [9] Mg ...
Magnesium cyanide is a chemical compound with the formula Mg(CN) 2. It is a toxic white solid. Unlike calcium isocyanide, the cyanide ligands prefer to coordinate at carbon, with a 0.3‑kcal/mol isomerization barrier. [1] When this salt is heated to 500 °C, it decomposes to magnesium nitride. [2]
Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity.
