Water is called the “universal solvent” because it has the ability to dissolve more substances than any other liquid. This property is due to its polar nature and the ability to form hydrogen bonds. Here’s why:
Polarity: Water molecules have a partial positive charge on one side (hydrogen atoms) and a partial negative charge on the other side (oxygen atom). This polarity allows water to interact with various charged particles, including ions and other polar molecules.
Hydrogen Bonding: The hydrogen bonds that form between water molecules and other substances facilitate the dissolving process. When a substance is placed in water, the water molecules surround the particles of the substance, separating and shielding them from each other, leading to dissolution.
Versatility: Water can dissolve a wide range of substances, including salts, sugars, acids, alkalis, and gases, making it incredibly versatile.
Because of these characteristics, water is capable of dissolving many different types of molecules, which is essential for various biological, chemical, and environmental processes.
