In an ammonia absorption system, what is absorbed by the weak aqua?

• A. Liquid ammonia
• B. Vaporized ammonia
• C. Solid ammonia
• D. Cold vapor

Answer: (B)

In an ammonia absorption system, the weak aqua absorbs vaporized ammonia. This process is fundamental to the operation of the absorption system. The weak aqua, which is essentially a diluted solution of ammonia in water, interacts with the vaporized ammonia to create a stronger solution of ammonia. The absorption is driven by the difference in ammonia concentration between the vapor phase and the liquid phase. As the vaporized ammonia comes into contact with the weak aqua, it dissolves in the liquid, effectively being absorbed. This process is vital because it allows for the continual absorption and circulation of ammonia within the system, facilitating the refrigeration cycle. The efficiency of this absorption is impacted by factors like temperature and pressure, which influence how much ammonia can be absorbed into the weak aqua.
