Classical science teaches us that water is composed of the chemical elements hydrogen and oxygen and exists in gaseous, liquid, and solid states. There is a now awareness of a fourth state of water – a plasma. Water is one of the most plentiful and essential of compounds. It is vital for life, participating in virtually every process that occurs in plants and animals. Although the molecules of water are simple in structure (H2O), the physical and chemical properties of the compound are extraordinarily complicated.
Water is a colourless, tasteless, and odourless liquid at room temperature. One of its most important properties is its ability to dissolve many other substances. The versatility of water as a solvent is essential to living organisms. Life is believed to have originated in the world’s oceans, which are complicated solutions.
