  2. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  3. Iodine - Wikipedia

    en.wikipedia.org/wiki/Iodine

    The melting and boiling points of iodine are the highest among the halogens, conforming to the increasing trend down the group, since iodine has the largest electron cloud among them that is the most easily polarised, resulting in its molecules having the strongest Van der Waals interactions among the halogens.

  4. Boiling points of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Boiling_points_of_the...

    This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 11 Na sodium; use: 1156.090 K ...

  5. Melting points of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Melting_points_of_the...

    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.

  6. Vapor pressures of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressures_of_the...

    The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere. log refers to log base 10 (T/K) refers to temperature in Kelvin (K) (P/Pa) refers to pressure in Pascal (Pa)

  7. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate serves as a flux for silica (SiO 2, melting point 1,713 °C), lowering the melting point of the mixture to something achievable without special materials. This "soda glass" is mildly water-soluble, so some calcium carbonate is added to the melt mixture to make the glass insoluble.

  8. Sodium iodide - Wikipedia

    en.wikipedia.org/wiki/Sodium_iodide

    Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice. It is used mainly as a nutritional supplement and in organic chemistry.

  9. Lithium iodide - Wikipedia

    en.wikipedia.org/wiki/Lithium_iodide

    Melting point: 469 °C (876 °F; 742 K) Boiling point: 1,171 °C (2,140 °F; 1,444 K) Solubility in water. ... or LiI, is a compound of lithium and iodine.
