Question

Why is solubility of ammonia in water very high?

Answer 1

The solubility of ammonia in water is very high because:

1. Ammonia molecules form hydrogen bonds with water molecules.
2. The N-H bond in ammonia is polar, causing strong attraction to water.
3. This hydrogen bonding helps ammonia dissolve extensively, up to 1300 volumes in one volume of water at standard conditions.
4. Other hydrides do not form such bonding, so they are less soluble.

Thus, hydrogen bonding is the key reason for ammonia’s high solubility in water.
