Chlorine is a chemical element; ... Thus, the melting and boiling points of chlorine are intermediate between those of fluorine and bromine: chlorine melts at −101. ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
The earliest method of synthesis was to treat mercury(II) oxide with chlorine gas. [3] However, this method is expensive, as well as highly dangerous due to the risk of mercury poisoning. 2 Cl 2 + HgO → HgCl 2 + Cl 2 O. A safer and more convenient method of production is the reaction of chlorine gas with hydrated sodium carbonate at 20–30 ...
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 17 Cl chlorine (Cl 2) use: 239. ...
Melting point: −96.7 °C (−142.1 °F; 176.5 K) Boiling point: ... DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C ...
