It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the most abundant substance on the surface of Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. Water and Properties of water are hydrogen compounds, inorganic solvents, oxides, oxygen compounds and Triatomic molecules.
