Explanation: Since air won’t dissolve in water the affinity of nitrogen towards the water will be more which converts ammonia into ammonium solution. But in other options the hydrocarbons easily dissolves in polar solvents.

Understanding Absorption
Absorption is a process where one substance is taken up by another. In chemical engineering, this typically refers to gases being absorbed in liquids. Among the options provided, option 'A' (Ammonia and air in solvent water) is the most common example of absorption.
Reasons for Option A Being Most Common
- High Solubility of Ammonia: Ammonia (NH3) is highly soluble in water, making it an ideal candidate for absorption processes. Its solubility allows for significant amounts of ammonia to be absorbed in water, facilitating various applications in industries.
- Formation of Ammonium Hydroxide: When ammonia dissolves in water, it reacts to form ammonium hydroxide (NH4OH), which is a crucial component in many chemical processes. This reaction enhances the effectiveness of ammonia absorption.
- Industrial Relevance: Ammonia absorption in water is widely used in industries, such as fertilizer production and wastewater treatment. This makes the process not only common but also essential in various applications.
- Environmental Impact: The absorption of ammonia helps in controlling emissions and reducing environmental pollution, highlighting its importance in sustainability practices.
Comparison with Other Options
- Ammonia and Carbon Dioxide: While this combination is significant in certain contexts, the absorption of ammonia in water is more prevalent.
- Methane and Air: Methane is not significantly soluble in water, making this option less relevant for absorption processes.
- Methane and Carbon Dioxide: Similar to methane and air, this combination does not exhibit strong absorption characteristics in water.
By understanding these elements, it becomes clear why ammonia and air in solvent water is the most common example of absorption in chemical engineering.
