What is the name of experiment to show that a product obtained is a basic oxide
2Mgo+O2=2MgO
The experiment you are referring to is called the "Combustion of Magnesium" or the "Burning of Magnesium" experiment. The objective of the experiment is to show that when magnesium (Mg) reacts with oxygen (O2), it forms magnesium oxide (MgO), which is a basic oxide.
To perform this experiment, you will need the following materials:
1. Magnesium ribbon (Mg)
2. Bunsen burner or a source of heat
3. Crucible or a heat-resistant container
4. Tongs for handling the crucible
5. Safety goggles and gloves for protection
6. A balance to measure the mass of magnesium
Here's a step-by-step guide to carry out the experiment:
1. Put on your safety goggles and gloves to protect yourself from potential hazards.
2. Measure the mass of the crucible using a balance and record it.
3. Take a small piece of magnesium ribbon and measure its mass using the same balance. Record this value as well.
4. Place the magnesium ribbon inside the crucible using the tongs.
5. Position the crucible on top of the Bunsen burner or heat source. Make sure it is stable and won't topple over during the experiment.
6. Light the Bunsen burner and adjust the flame to have a blue, non-luminous flame.
7. Gradually heat the crucible with the magnesium ribbon inside. Keep the flame on the crucible until the magnesium ribbon starts burning.
8. Observe the reaction. The magnesium ribbon will burn with a bright white light and produce a white, powdery residue.
9. Once the reaction is complete, allow the crucible to cool down for a few minutes.
10. Measure the mass of the crucible with the residue of magnesium oxide. Record this value.
11. Calculate the difference in mass before and after the reaction. The increase in mass corresponds to the mass of oxygen that combined with magnesium to form magnesium oxide.
12. Finally, name the product obtained as magnesium oxide, which is a basic oxide.
Please note that this experiment involves high temperatures and the combustion of magnesium can be dangerous. Therefore, proper precautions should be taken, and it is advised to perform the experiment under the supervision of a knowledgeable individual or in a controlled laboratory setting.
