The melting point (or, rarely, liquefaction point) of a solid is the temperature at
which it changes ... Tantalum hafnium carbide (Ta4HfC5) is a refractory
compound with a very high melting point of...
The melting point is an important physical property of a compound. The melting
point can be used to identify a substance and as an indication of its purity.
Determining the melting point of a compound is one way to test if the substance is
pure. A pure substance generally has a melting range (the difference between ...
For example, the molecule carbon tetrachloride is a non-polar covalent molecule,
CCl4. It's melting point is -23°C. By contrast, the ionic solid NaCl has a melting ...
Formula, melting point, boiling point, density and refractive index. Hydrated forms
are indicated thus: para-Toluenesulphonic acid + H2O, and the molecule(s) of ...
A pure organic compound usually melts over a range of two degrees or less. If
the melting point of a pure compound is within a degree of the value found a lab ...
Melting points are characteristic of a particular compound, and in fact are often
used to help identify an unknown. Of course with so many thousands of known ...
