Missing physicochemical properties for chemicals
When adding missing physicochemical properties, please take the following into account:
The following links prioritize chemical compounds that are listed in most Wikis
(Wikipedias, Wikimedia Commons, etc). To go to the Wikidata page for each item, click its name
below, which will lead to its Scholia page which links to the Wikidata page via the
Q number link at the top.
Missing Boiling Points
The
boiling point is the temperature
at which boiling occurs under a pressure of one bar.
Typical units given include degrees
Kelvin and degrees
Celsius. Because
it depends on the pressure, this is often also given, as shown in
these examples.
Missing Melting Points
The
melting point is the temperature at which a compound melts. Typical units given include degrees
Kelvin and degrees
Celsius. It is
often found for organic chemicals as part of their unique characterization. Check out
these examples.
Missing Mass
Missing Solubility
The
solubility
of a compound is always in some solvent and depending on the temperature. The
latter two are therefore commonly given as qualifiers, as for this
example.
The
enthalpy of formation
is a measure of the stability of the compound.
Missing Vapor Pressure
Missing Molar Entropy
Missing Density
Missing Chemical Structure
Missing Flash Point
Missing pKa
Missing Combustion Enthalpy
Missing IDLH
The
Immediately Dangerous to Life and Health value
(IDLH) is an indication provided by the U.S.
CDC about the danger of the compound.
