Understanding Oxygen Absorption
In the context of the given options, the ability to quickly absorb oxygen is a critical property of certain chemical solutions. Let's analyze the options provided:
1. Alkaline Solution of Pyrogallol
- Pyrogallol, when combined with an alkaline solution, has a high affinity for oxygen due to its chemical structure.
- It reacts with oxygen in the presence of alkali, forming a stable compound and effectively removing oxygen from the environment.
- This property makes pyrogallol a common choice in laboratory settings for oxygen absorption studies.
2. Concentrated H2SO4
- While concentrated sulfuric acid is a strong dehydrating agent, it does not specifically absorb oxygen efficiently.
- Its primary role is to absorb water and act as a catalyst in various chemical reactions, rather than to interact directly with oxygen.
3. Lime Water
- Lime water, a saturated solution of calcium hydroxide, does not absorb oxygen.
- It primarily reacts with carbon dioxide to form calcium carbonate, making it unsuitable for oxygen absorption.
4. Alkaline Solution of CuSO4
- An alkaline solution of copper sulfate can participate in redox reactions but is not as effective in absorbing oxygen as pyrogallol.
- Its interaction with oxygen is limited compared to the strong reactivity of alkaline pyrogallol.
Conclusion
- Among the options, the alkaline solution of pyrogallol is the most efficient in quickly absorbing oxygen due to its specific chemical properties. Thus, option 'A' is the correct answer.
