Description
Water appears as a clear, nontoxic liquid composed of hydrogen and oxygen, essential for
life and the most widely used solvent. Include water in a mixture to learn how it could react
with other chemicals in the mixture.
CAMEO Chemicals
Water is an oxygen hydride consisting of an oxygen atom that is covalently bonded to
two hydrogen atoms It has a role as an amphiprotic solvent, a member of greenhouse gas, a
human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and
a mouse metabolite. It is an oxygen hydride, a mononuclear parent hydride and an
inorganic hydroxy compound. It is a conjugate base of an oxonium. It is a conjugate acid of
a hydroxide.
ChEBI
Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes,
oceans and rain, and is the major constituent of the fluids of organisms. As a chemical
compound, a water molecule contains one oxygen and two hydrogen atoms that are
connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure,
but it often co-exists on Earth with its solid state, ice; and gaseous state, steam (water vapor).
