The element magnesium is often in fireworks because it burns with bright white light. It adds white sparks and hence, improves the overall brilliance of a firework.
Properties of Magnesium
- Magnesium metal and its alloys are explosive in nature. They are highly flammable in pure form, powder form, or ribbon form
- Magnesium reacts violently with water
- When magnesium metal is burned it reacts with the oxygen present in the air. Magnesium and oxygen react with each other to form magnesium oxide which is a white powder. Magnesium gives its 2 electrons to the oxygen to form this powdered product.
The reaction is as follows:
[tex]2Mg (s) + O_2 (g) \rightarrow 2MgO(s) + energy[/tex]
The reaction is exothermic in nature.
- It can also reduce water to H₂ gas
[tex]Mg(s)+ 2H_2O \rightarrow Mg(OH)_2(s) + H_2 (g)[/tex]
- Magnesium reacts with carbon dioxide to form carbon
[tex]Mg(s)+CO_2 \rightarrow 2MgO(s)+ C(s)[/tex]
As magnesium is highly flammable and burns with white bright light, hence it is used in fireworks to improve its overall experience.
