Ammonia Gas High Solubility in Water Reason
The high solubility of ammonia in water is due to the high solubility of ammonia in water.
First, ammonia and water molecules can form hydrogen bonds. Nitrogen in ammonia molecules has solitary pairs of electrons, while hydrogen in water molecules is partially positively charged, and the two meet, thus forming hydrogen bonds. The force of this hydrogen bond makes ammonia molecules closely connected to water molecules, making ammonia easily soluble in water.
Second, ammonia molecules are structurally compatible with water molecules. Ammonia molecules are triangular conical and polar; water molecules are V-shaped and also polar. The polarities of the two match, and according to the principle of "similar miscibility", polar solute ammonia is easily soluble in polar solvent water.
Furthermore, ammonia can react chemically with water. Ammonia dissolves in water, and some reactions with water produce ammonia monohydrate ($NH_3\ cdot H_2O $). This reaction shifts the dissolution balance of ammonia in water to the right, causing more ammonia to dissolve into water.
From the above, it can be seen that the formation of hydrogen bonds, the fit of structures and the initiation of chemical reactions are the main reasons for the high solubility of ammonia in water.
