Which of the following statements about the reaction of a non-metallic oxide with a base is/are correct?

Statement I: The reaction of non-metallic oxide with base produces salt and water.

Statement II: Non-metallic oxides are acidic in nature.  

The correct answer is 3) Both statements I and II are correct.

Key Points

• Non-metallic oxides such as CO₂ and SO₂ react with bases to form salt and water, demonstrating their acidic nature.
• Statement I is correct as it describes the neutralization reaction between a non-metallic oxide and a base.
• Statement II is correct as non-metallic oxides are indeed acidic in nature, meaning they react with bases.
• Examples include CO₂ reacting with NaOH to form Na₂CO₃ (sodium carbonate) and water.

Additional Information

• Acid-Base Reactions:
  • Acid-base reactions involve the transfer of protons (H⁺) from the acid to the base.
  • These reactions result in the formation of water and a salt.
• Examples of Non-Metallic Oxides:
  • Carbon dioxide (CO₂), sulfur dioxide (SO₂), and nitrogen dioxide (NO₂) are common non-metallic oxides.
  • These oxides typically react with water to form acids.
• Neutralization Reactions:
  • In a neutralization reaction, an acid and a base react to form water and a salt.
  • This type of reaction is essential in various industrial and biological processes.
• Properties of Acids and Bases:
  • Acids have a sour taste and can turn blue litmus paper red.
  • Bases have a bitter taste and can turn red litmus paper blue.
