FAQ

What makes water so unique?

Water's unique properties stem from its molecular structure. Two hydrogen atoms bond to a single oxygen atom at an angle of approximately 104.5°, creating a slightly negative charge on the oxygen and a slightly positive charge on the hydrogens. This polarity allows water molecules to form up to four hydrogen bonds with neighboring water molecules, giving it a dynamic, cage-like structure.

How does water's structure impact its properties?

The tetrahedral arrangement and hydrogen bonding capabilities of water molecules contribute to its remarkable properties, including:

• High surface tension: Allows for water droplets to form and insects to walk on water.
• Unique phase behavior: Exists in solid (ice), liquid (water), and gaseous (vapor) states within Earth's temperature range.
• Excellent solvency: Dissolves a wide range of substances, earning it the title of "universal solvent."
• High heat capacity: Water can absorb and release large amounts of heat, moderating Earth's temperature.

Here's how water's molecular properties can help tackle key global issues:
