Ammonia Hydrogen Bonding with Water
The hydrogen bond between ammonia and water. Ammonia molecules contain nitrogen atoms with solitary pairs of electrons, and hydrogen atoms are partially positively charged. The oxygen atoms in water molecules are highly electronegative, and hydrogen is also partially positively charged. When ammonia and water meet, the solitary pairs of electrons of ammonia nitrogen atoms will form hydrogen bonds with the hydrogen atoms of water molecules. This effect causes ammonia to have a certain solubility in water, because the hydrogen bond prompts ammonia molecules and water molecules to attract and bind to each other. After ammonia and water form hydrogen bonds, the original intermolecular forces between the two molecules are changed, which affects physical properties such as boiling point and solubility. From a microscopic perspective, hydrogen bonds build bridges between ammonia and water molecules, making their arrangement and distribution more orderly, and play a key role in the chemical and physical behavior of related systems.
