  2. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    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. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.

  3. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl. [ 31 ] [ 32 ] [ 33 ] Hydrochloric acid as the binary (two-component) mixture of HCl and H 2 O has a constant-boiling azeotrope at 20.2% HCl and 108.6 °C (381.8 K; 227.5 °F).

  4. Henry's law - Wikipedia

    en.wikipedia.org/wiki/Henry's_law

    In his 1803 publication about the quantity of gases absorbed by water, [1] William Henry described the results of his experiments: … water takes up, of gas condensed by one, two, or more additional atmospheres, a quantity which, ordinarily compressed, would be equal to twice, thrice, &c. the volume absorbed under the common pressure of the atmosphere.

  5. Chloroethane - Wikipedia

    en.wikipedia.org/wiki/Chloroethane

    Chloroethane is produced by hydrochlorination of ethylene: [11]. C 2 H 4 + HCl → C 2 H 5 Cl. At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, from ethane and chlorine, or from ethanol and phosphorus trichloride, but these routes are no longer economical.

  7. Greenhouse gas - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas

    Water vapor is the most important greenhouse gas overall, being responsible for 41–67% of the greenhouse effect, [32] [33] but its global concentrations are not directly affected by human activity. While local water vapor concentrations can be affected by developments such as irrigation , it has little impact on the global scale due to its ...

  8. Thorium - Wikipedia

    en.wikipedia.org/wiki/Thorium

    At standard temperature and pressure, thorium is slowly attacked by water, but does not readily dissolve in most common acids, with the exception of hydrochloric acid, where it dissolves leaving a black insoluble residue of ThO(OH,Cl)H. [11] [50] It dissolves in concentrated nitric acid containing a small quantity of catalytic fluoride or ...

  9. Baumé scale - Wikipedia

    en.wikipedia.org/wiki/Baumé_scale

    Baumé degrees (light) was calibrated with 0 °Bé (light) being the density of 10% NaCl in water by mass and 10 °Bé (light) set to the density of water. Consider, at near room temperature: +100 °Bé (specific gravity, 3.325) would be among the densest fluids known (except some liquid metals), such as diiodomethane .
