Why do we clean magnesium ribbon before burning?

Question

Answer

Magnesium ribbon must be cleaned before burning in air so that the layer of magnesium oxide (which is formed due to reaction of magnesium with air) can be removed in order to get the desired chemical reaction.

Answer

Yaa they r obviously correct

Answer

Magnesium ribbon is cleaned with Sandpaper before burning because in open air layer of various oxides and carbonates of magnesium are formed on the service and as a result the magnesium ribbon do not burn properly so to get proper results it is cleaned before burning

Answer

To remove the oxide layer formed slowly when kept at open. The oxide layer is removed to increase the reactivity.

Answer

As there is a outer covering of oxide layer on mg ribbon because of which mg ribbon is not able to burn properly so ribbon is clean ,to clean the oxide layer so the results are good

Answer

Importance of Cleaning Magnesium Ribbon Before Burning
Cleaning the magnesium ribbon before burning is essential to ensure a successful and efficient combustion process. Here are the reasons why it is important to clean the magnesium ribbon before burning:

1. Removal of Oxidized Layer
- Magnesium metal tends to form an oxide layer on its surface when exposed to air. This oxide layer can act as a barrier, hindering the combustion process and preventing the magnesium from burning completely.
- By cleaning the magnesium ribbon, we can remove this oxide layer, allowing the magnesium to react more readily with oxygen during the burning process.

2. Enhancing Surface Area
- Cleaning the magnesium ribbon helps in increasing its surface area by removing any impurities, dirt, or contaminants that may be present on the surface.
- A larger surface area of the magnesium ribbon facilitates better interaction with oxygen molecules during combustion, leading to a more vigorous and complete burning reaction.

3. Ensuring Safety
- Cleaning the magnesium ribbon before burning helps in ensuring safety during the combustion process. Any impurities or contaminants on the surface of the magnesium ribbon can lead to unpredictable reactions or unwanted side effects.
- By thoroughly cleaning the magnesium ribbon, we can minimize the risk of accidents or hazardous situations that may arise due to impurities present on the surface.
In conclusion, cleaning the magnesium ribbon before burning is crucial for promoting a clean and efficient combustion process, enhancing the reactivity of magnesium with oxygen, and ensuring safety during the burning reaction. By following this practice, we can achieve optimal results and minimize potential risks associated with impurities on the magnesium surface.
