  2. Water - Wikipedia

    en.wikipedia.org/wiki/Water

    'Dihydrogen monoxide' is a technically correct but rarely used chemical name of water. This name has been used in a series of hoaxes and pranks that mock scientific illiteracy. This began in 1983, when an April Fools' Day article appeared in a newspaper in Durand, Michigan. The false story consisted of safety concerns about the substance. [250]

  3. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Using chemical nomenclature for type I ionic binary compounds, water would take the name hydrogen monoxide, [105] but this is not among the names published by the International Union of Pure and Applied Chemistry (IUPAC). [101] Another name is dihydrogen monoxide, which is a rarely used name of water, and mostly used in the dihydrogen monoxide ...

  4. Hydrate - Wikipedia

    en.wikipedia.org/wiki/Hydrate

    In organic chemistry, a hydrate is a compound formed by the hydration, i.e. "Addition of water or of the elements of water (i.e. H and OH) to a molecular entity". [5] For example: ethanol, CH3−CH2−OH, is the product of the hydration reaction of ethene, CH2=CH2, formed by the addition of H to one C and OH to the other C, and so can be ...

  5. Chemical substance - Wikipedia

    en.wikipedia.org/wiki/Chemical_substance

    Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bonded to a single oxygen atom (i.e. H 2 O).

  6. Hydroxide - Wikipedia

    en.wikipedia.org/wiki/Hydroxide

    Hydroxide is a diatomic anion with chemical formula OH −. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile, and a catalyst.

  7. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using chemical symbols for the chemical elements, and subscripts to indicate the number of atoms involved. For example, water is composed of two hydrogen atoms bonded to one oxygen atom: the chemical formula is H 2 O.

  8. Distilled water - Wikipedia

    en.wikipedia.org/wiki/Distilled_water

    Distilled water. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water.

  9. Chemical bonding of water - Wikipedia

    en.wikipedia.org/wiki/Chemical_bonding_of_water

    Chemical bonding of water. Water (H2O) is a simple triatomic bent molecule with C 2v molecular symmetry and bond angle of 104.5° between the central oxygen atom and the hydrogen atoms. Despite being one of the simplest triatomic molecules, its chemical bonding scheme is nonetheless complex as many of its bonding properties such as bond angle ...
