2Mg +O2 > 2MgO

Write experiment to prove that the product is basic oxide?

Add water, test with litmus paper.

There is any other method or not

Probably several but you can't beat this one for simplicity. Any other method that will test the acidity/basicity will work.

Thanks you lot Sir

To experimentally prove that the product of the reaction 2 Mg + O2 → 2 MgO is a basic oxide, you can perform a simple test using litmus paper. Here's an experiment you can follow:

Materials needed:
1. Magnesium ribbon or powder (2g)
2. Oxygen source (e.g., oxygen gas cylinder or air)
3. Crucible and Bunsen burner (or a suitable heat source)
4. Litmus paper (both red and blue)

Procedure:
1. Start by obtaining a small piece of magnesium ribbon or powder. Make sure the magnesium is clean and free from any oxide coating.

2. Place the magnesium in a crucible.

3. Ignite the Bunsen burner or heat source and heat the crucible containing the magnesium.

4. As the magnesium reacts with oxygen in the air, it will ignite and burn, forming magnesium oxide.

5. Allow the reaction to complete, ensuring that all the magnesium has reacted to form magnesium oxide.

6. Once the reaction is complete, carefully remove a small amount of the magnesium oxide product. Be cautious as both magnesium and magnesium oxide can be hot.

7. Take a piece of red litmus paper and dip it into a small amount of water.

8. Touch the wet red litmus paper to the magnesium oxide sample.

9. Observe the reaction of the litmus paper. If the litmus paper turns blue or remains unchanged, it indicates that the product (magnesium oxide) is a basic oxide.

Explanation:
In the reaction between magnesium and oxygen, magnesium combines with oxygen to form magnesium oxide. Magnesium oxide is a basic oxide, meaning it has basic properties.

To confirm this, we perform the litmus paper test. Litmus paper is an indicator that changes color in the presence of an acid or base. Red litmus paper turns blue in basic substances, while blue litmus paper turns red in acidic substances.

By touching the wet red litmus paper to the magnesium oxide product, if the paper turns blue or remains unchanged, it indicates that the product is basic. This confirms that magnesium oxide is a basic oxide.
