* Highly Reactive: Magnesium is a highly reactive metal. It readily reacts with oxygen in the air, forming magnesium oxide (MgO). This reaction is exothermic and can generate significant heat, potentially leading to a fire or explosion.
* Moisture Sensitivity: Magnesium also reacts with water, forming magnesium hydroxide (Mg(OH)2) and releasing hydrogen gas. This reaction is also exothermic and can be dangerous.
* Protection from Oxidation: Kerosene or mineral oil creates a barrier between the magnesium metal and the air and moisture, preventing these reactions from occurring.
Storing Magnesium Safely:
* Kerosene or Mineral Oil: These are the preferred storage options due to their non-reactivity with magnesium.
* Sealed Containers: Always store magnesium in airtight containers to prevent moisture from entering.
* Avoid Contact with Water: Never store magnesium in areas where it could come into contact with water.
* Proper Labeling: Label containers clearly with the name of the substance and appropriate warnings.
Note: While kerosene is a common storage medium for magnesium, other options like mineral oil may be preferable due to their lower flammability.
Safety is paramount when handling and storing magnesium. Always consult safety data sheets (SDS) and follow recommended storage practices.
