Three form of water; liquid, solid (ice) and gas (water vapour). Most of the cell itself surrounded by water about 70%-95%. Besides, molecules of water allowed to interact with others molecules.

Hydrogen bond in water molecule
Water molecules (H2O-H2O) are held together by hydrogen bonds.

Thermal & solvent properties of water

Ionization of water
There are hydrogen ion (H+) formed when hydrogen bond shifting between the water molecules.
Water molecule are amphiprotic that can act as acid and base:
Water self-ionization are reversible reaction. |
