Why is magnesium ribbon cleaned?

Question

Answer

Magnesium ribbon should be cleaned with sandpaper before burning in the air because of the following reasons:

*Magnesium is a very reactive element which rapidly reacts with oxygen in the air to form a white layer of magnesium oxide and this layer will not burn.

*To remove the Magnesium oxide layer from the ribbon which may prevent or slow down the burning of magnesium ribbon.

*Unwanted impurities deposited on the magnesium ribbon can be removed and only pure magnesium can be used for the reaction.

Answer

Magnesium ribbon should be cleaned before using it in experiments because :-
#The ribbon of magnesium gets deposited with a layer of magnesium oxide when it is kept in open air.
#Pure magnesium is used in experiments not the impure one containing a lot of impurities which may act as obstacles during the experiment.

Answer

¶¶ To remove protective layer so it can react easily

Answer

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

Answer

Inorder to remove magnesium oxide layer to perform desired chemical reaction

Answer

Introduction:
Magnesium ribbon is a highly reactive metal that easily reacts with oxygen and forms magnesium oxide. To prevent this reaction from occurring, magnesium ribbon is cleaned before it is used. In this response, we will explain in detail why magnesium ribbon is cleaned.

The need to clean magnesium ribbon:
Magnesium ribbon is usually stored in airtight containers to prevent it from reacting with oxygen in the air. However, when the magnesium ribbon is removed from its container, it can still react with any moisture, dirt or other contaminants that may be present on its surface. This can cause the magnesium ribbon to burn or react uncontrollably, which can be dangerous.

Cleaning Process:
To prevent this from happening, magnesium ribbon is cleaned before it is used. The cleaning process involves removing any dirt or moisture that may be present on the surface of the ribbon. This is done by using a piece of sandpaper or a wire brush to remove any oxidation or other contaminants that may be present on the surface of the ribbon.

Why Cleaning is Important:
Cleaning the magnesium ribbon ensures that it is free from any contaminants that might cause it to react uncontrollably. This makes it safer to handle and use in experiments. In addition, cleaning the ribbon ensures that it reacts with other substances in a predictable and controlled manner.

Conclusion:
In conclusion, magnesium ribbon is cleaned to prevent it from reacting uncontrollably with moisture, dirt, or other contaminants that may be present on its surface. Cleaning the ribbon ensures that it is safe to handle and use in experiments, and that it reacts in a predictable and controlled manner.

Unwanted impurities deposited on the magnesium ribbon can be removed and only pure magnesium can be used for the reaction

Answer

See, I'll clear your doubt sis!!!. Magnesium ribbon reacts with oxygen and leads to the formation of white layer of Magnesium Oxide. White layer is also called dust particles. When the dust particles sits on the magnesium ribbon, what happens next?. The magnesium ribbon cannot reacts in order to perform chemical reaction due to the secretion of dust particles on the magnesium ribbon when it goes to reacts with the oxygen present in the atmosphere !!!.

Hope you have understand my words sis!!!!!.

Answer

Magnesium is a very reactive metal, which when come in contact with oxygen form a layer of magnesium oxide(Mgo).which prevents the burning of magnesium ribbon that is why, a magnesium ribbon is cleaned before burning it using Sandpaper.

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

Magnesium ribbon must be cleaned by rubbing sand paper on it bcz an oxide layer is formed on magnesium due to reaction with atmosphere.
and this oxide layer does not allow magnesium to burn easily. SO , in order to complete the further chemical reaction it must be cleaned.
