Which of the following method is not used in preparing a base?a)Burnin...
Introduction:
In chemistry, a base is a substance that can accept protons (H+) or donate a pair of electrons. Bases are used in various chemical reactions and are prepared by different methods. However, there is one method that is not used in preparing a base, which is adding water to a metal oxide.
Explanation:
Let's discuss each method mentioned in the options and understand why they are used in preparing a base.
Burning of metal in air:
- This method is used to prepare a base known as a metal oxide.
- When a metal reacts with oxygen in the air, it forms an oxide.
- Metal oxides are basic in nature and can be used as bases in various reactions.
Reaction between an acid and base:
- This method is commonly used to prepare a base.
- When an acid reacts with a base, they neutralize each other and form a salt and water.
- The salt formed in this reaction can act as a base.
Heating metal carbonates:
- This method is also used to prepare a base.
- Metal carbonates, when heated, decompose to form metal oxides and carbon dioxide gas.
- Metal oxides obtained in this process can be used as bases.
Adding water to a metal oxide:
- This method is not used in preparing a base.
- Adding water to a metal oxide forms a salt and water, but it does not change the basic nature of the metal oxide.
- The resulting product is not a base, but a neutral compound.
Conclusion:
In summary, adding water to a metal oxide is not a method used in preparing a base. The other methods mentioned, such as burning a metal in air, reacting an acid with a base, and heating metal carbonates, are commonly used to prepare bases.
