Why does Magnesium Float in Water
Magnesium is a reactive metal that reacts with water to form magnesium hydroxide and hydrogen gas. When magnesium is initially placed in water, it sinks due to its high density. However, after some time, it starts to float on the surface of the water.
Reasons for Magnesium Floating in Water
Conclusion
In conclusion, the floating of magnesium in water is a result of the formation of magnesium hydroxide, production of hydrogen gas, and the surface tension of water. These factors combined cause the magnesium to displace water and float on the surface.
Magnesium is a reactive metal that reacts with water to form magnesium hydroxide and hydrogen gas. When magnesium is initially placed in water, it sinks due to its high density. However, after some time, it starts to float on the surface of the water.
Reasons for Magnesium Floating in Water
- Formation of Magnesium Hydroxide: When magnesium reacts with water, it forms magnesium hydroxide which is less dense than water. This causes the magnesium to displace some water and float on the surface.
- Hydrogen Gas Production: As magnesium reacts with water, hydrogen gas is produced. The bubbles of hydrogen gas adhere to the surface of the magnesium, reducing its overall density and causing it to float.
- Surface Tension: Surface tension of water allows the magnesium to float. The surface tension of water creates an invisible film on the surface which supports the magnesium and prevents it from sinking.
Conclusion
In conclusion, the floating of magnesium in water is a result of the formation of magnesium hydroxide, production of hydrogen gas, and the surface tension of water. These factors combined cause the magnesium to displace water and float on the surface.
