Magnesium ribbon is a common laboratory material made from pure magnesium. It is typically supplied in thin strips or coils, making it easy to cut and handle. Magnesium ribbon has several uses and is involved in various types of experiments due to its distinct chemical and physical properties.


Magnesium Ribbon

1. Combustion Experiments

  • Demonstration of Combustion: Magnesium ribbon is often ignited to demonstrate a combustion reaction. It burns with an intense white flame, forming magnesium oxide (MgO) and releasing a significant amount of light and heat.
  • Illustrating Exothermic Reactions: The burning of magnesium is a clear example of an exothermic reaction, showcasing the release of energy in the form of light and heat.

2. Chemical Reactions

  • Reaction with Acids: Magnesium reacts vigorously with acids like hydrochloric acid to produce hydrogen gas and magnesium chloride (MgCl₂). This reaction is used to study reactivity and gas production.
  • Single Displacement Reactions: Magnesium can displace less reactive metals from their compounds in solution, illustrating the activity series of metals.

3. Thermite Reactions

  • Ignition Source: Due to its high burning temperature, magnesium ribbon can be used to ignite thermite mixtures, which involve the reaction of metal oxides with aluminum to produce molten metal and a great deal of heat.

4. Synthesis of Magnesium Compounds

  • Formation of Magnesium Hydroxide: When reacted with water, magnesium forms magnesium hydroxide and hydrogen gas, which can demonstrate the reactivity of magnesium with water.
  • Production of Magnesium Sulfate: By reacting magnesium with sulfuric acid, magnesium sulfate (Epsom salt) can be produced, which is used in various applications.

5. Educational Demonstrations

  • Redox Reactions: Magnesium is used to demonstrate oxidation-reduction reactions, showing the transfer of electrons between substances.
  • Stoichiometry: It can be used to illustrate stoichiometric principles in chemical reactions by measuring the reactants and products.

6. Energy Studies

  • Heat and Light Production: The intense heat and light produced by burning magnesium can be used to study energy transformations and the characteristics of different types of energy.

7. Analytical Chemistry

  • Gravimetric Analysis: Magnesium can be used in gravimetric analysis, where its reaction with other substances is used to isolate and weigh a product, helping determine the composition of a sample.

Safety Considerations

  • Eye Protection: Always wear proper eye protection, such as safety goggles, when burning magnesium to protect against the bright light.
  • Fire Safety: Use appropriate fire extinguishers (Class D) for metal fires. Do not use water or CO₂ extinguishers on burning magnesium.
  • Handling: Handle with care to avoid skin contact and inhalation of dust or fumes.

Storage and Disposal

  • Storage: Store magnesium ribbon in a dry, cool place away from moisture and oxidizing agents.
  • Disposal: Neutralize small amounts with dilute acids before disposal. Follow local hazardous waste disposal regulations for larger quantities.

When using magnesium ribbon in a laboratory, it’s essential to follow specific safety precautions to prevent accidents and ensure a safe working environment. Here are key safety measures to consider:

General Handling

  1. Avoid Direct Contact: Handle magnesium ribbon with clean, dry hands or use gloves to prevent contamination and irritation.
  2. Ventilation: Conduct experiments involving magnesium ribbon in a well-ventilated area or under a fume hood to avoid inhaling any fumes or dust produced during reactions.

Personal Protective Equipment (PPE)

  1. Eye Protection: Wear safety goggles or a face shield to protect your eyes from the intense light and potential sparks produced when burning magnesium.
  2. Gloves: Use appropriate gloves to prevent skin contact, especially when handling acids or other reactive chemicals alongside magnesium.
  3. Lab Coat: Wear a lab coat to protect your skin and clothing from any potential splashes or sparks.

Combustion Safety

  1. Bright Light Caution: Avoid looking directly at burning magnesium as it produces an extremely bright light that can cause eye damage. Use welding goggles or observe from a safe distance.
  2. Fire Extinguishers: Have a Class D fire extinguisher readily available, which is specifically designed for metal fires. Do not use water or carbon dioxide extinguishers as they can react with burning magnesium and exacerbate the fire.
  3. Fire Prevention: Keep flammable materials and chemicals away from the area where magnesium ribbon is being burned.

Chemical Reactions

  1. Acid Reactions: When reacting magnesium with acids, add the magnesium ribbon slowly to the acid to control the reaction rate and prevent splashing.
  2. Hydrogen Gas Production: Be aware that reactions between magnesium and acids produce hydrogen gas, which is highly flammable. Ensure the area is well-ventilated and free from ignition sources.


  1. Dry Environment: Store magnesium ribbon in a cool, dry place to prevent it from reacting with moisture in the air, which can cause corrosion and potentially hazardous conditions.
  2. Proper Containers: Use airtight containers to store magnesium ribbon, keeping it away from oxidizing agents and other reactive substances.


  1. Neutralization: For small amounts of magnesium ribbon, neutralize by carefully reacting it with a dilute acid to form a non-hazardous compound before disposal.
  2. Hazardous Waste: Dispose of larger quantities of magnesium ribbon according to local hazardous waste disposal regulations. Do not discard in regular trash or down the drain.

Emergency Procedures

  1. Spill Response: In case of a spill, collect the magnesium ribbon using non-sparking tools and dispose of it properly. Avoid creating dust.
  2. Fire Response: If a magnesium fire occurs, evacuate the area and use a Class D fire extinguisher. Do not attempt to extinguish with water or CO₂.
