  2. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.

  3. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrogen chloride can be generated in many ways, and thus several precursors to hydrochloric acid exist. The large-scale production of hydrochloric acid is almost always integrated with the industrial scale production of other chemicals , such as in the chloralkali process which produces hydroxide , hydrogen, and chlorine, the latter of which ...

  4. HCL - Wikipedia

    en.wikipedia.org/wiki/HCL

    Hollow-cathode lamp, a spectral line source used in physics and chemistry; Hydrochloric acid, a solution of hydrogen chloride in water; Hydrochloride, the salt of hydrochloric acid and an organic base; Hydrogen chloride, chemical formula HCl; Hypomania Checklist, a questionnaire used to screen for hypomania and bipolar spectrum disorders

  5. Diatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Diatomic_molecule

    The only chemical elements that form stable homonuclear diatomic molecules at standard temperature and pressure (STP) (or at typical laboratory conditions of 1 bar and 25 °C) are the gases hydrogen (H 2), nitrogen (N 2), oxygen (O 2), fluorine (F 2), and chlorine (Cl 2), and the liquid bromine (Br 2).

  6. Organochlorine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organochlorine_chemistry

    In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides. In the laboratory, the related reaction involving zinc chloride in concentrated ...

  7. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    Lone pairs in ammonia (A), water (B), and hydrogen chloride (C) A single lone pair can be found with atoms in the nitrogen group, such as nitrogen in ammonia. Two lone pairs can be found with atoms in the chalcogen group, such as oxygen in water. The halogens can carry three lone pairs, such as in hydrogen chloride.

  8. Electrolyte - Wikipedia

    en.wikipedia.org/wiki/Electrolyte

    Chloride levels are rarely measured except for arterial blood gas interpretations since they are inherently linked to sodium levels. One important test conducted on urine is the specific gravity test to determine the occurrence of an electrolyte imbalance .

  9. Chloric acid - Wikipedia

    en.wikipedia.org/wiki/Chloric_acid

    Another method is the heating of hypochlorous acid, producing chloric acid and hydrogen chloride: [citation needed] 3 HClO → HClO 3 + 2 HCl Any way it is produced, the acid may be concentrated up to 40% in a vacuum dessicator over H 2 SO 4 .
