What are some of the chemical properties of water?

Water is expressed by the molecular formula H2O and has a molar mass of 18.01 grams per mole. It has a density of 1 gram per cubic centimeter. The melting point of water is 32 degrees Fahrenheit, while the boiling point is reached at 211.96 degrees Fahrenheit.

Water is neither an acid nor a base; its pH is 7. Water in its solid state is called ice, and water in its gaseous state is known as water vapor. Scientists view water as essential to the formation of life. It makes up between 55 percent to 78 percent of the human body and covers 70 percent of the Earth's surface.
