Which of the following is not correctly matched?
- Water-gas: Hydrogen and carbon monoxide
- Oxidizing agent: hydrogen peroxide
- Reducing agent: Sulfuric acid
- Extraction of metals: Copper and tin
Hint:
Reducing agent: Sulphuric acid. Because sulphuric acid is a oxidising agent.
The correct answer is: Reducing agent: Sulfuric acid
Sulphuric acid act as an acid, an oxidizing agent and as a dehydrating agent. Sulphuric acid when heated, decomposes to give nascent oxygen which act as a strong oxidizing power.
