The melting point is not enough to definitely identify the compound because different compounds may have a similar melting point range. It all depends on the compounds. If you have a compound of acetanilide and flourene, the results will lead to similar melting points of 115 degrees Celsius and 116 degrees of Celsius. The ranges will be similar so it would be hard to definitely identify the compound.
What else can I help you with?
What information can be obtained from the melting point of a compound as an industrial chemist?
As an industrial chemist, the melting point of a compound can provide information about its purity. A sharp melting point indicates high purity, while a broader range could suggest impurities present. This data is crucial for quality control, identifying unknown substances, and determining the suitability of a compound for specific applications.
You are given the melting points of three unknown substances and are asked to predict which one is an ionic compound You would select the compound with the?
Highest melting point. (Note that this does not assure that the remaining compounds are not also ionic.)
What properties do scientists look for to identify an unknown substance?
Scientists look for properties such as density, boiling point, melting point, solubility, conductivity, and reactivity to help identify an unknown substance. By comparing these properties to known data in a database, scientists can often determine the identity of the unknown substance.
An unknown compound gave a melting point of 230 Cwhen the liquid solidifiedthe melting point was redetermined and found to be 131Cwhat might have caused this change?
Pressure can affect melting points.However, assuming that your conditions are the same, you may have changed the crystal structure of your compound.The crystal structure of a compound can affect its melting point. For example, diamond and graphite are both forms of elemental carbon. Diamond is a face-centered cubic structure. Graphite, however, is hexagonal. Graphite has a melting point of 3652°C, whereas diamond melts at 3550°C. When you liquified your compound, it because amorphous and lost its crystal structure. It may have recrystallized into a different structure.Heating may also have effected a chemical change. If you saw bubbles or a color change, you likely made a new compound.
Name several properties of matter that help you identify an unknown substance?
Density, melting point, boiling point, color, odor, solubility, and conductivity are important properties of matter that can aid in identifying an unknown substance. By comparing these characteristics to known data in reference tables, scientists can determine the identity of the unknown substance.
What the composition of a melting point mixture?
A melting point mixture typically consists of a 1:1 ratio of the compound being tested and a known standard compound, such as benzoic acid. The mixture is heated slowly to determine the melting point range of the unknown compound. By comparing the melting point range of the unknown compound to that of the standard, the identity or purity of the unknown compound can be determined.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
Melting point and boiling point determination can help in identifying unknown compounds by comparing the experimental values with known values in databases. A match can indicate the compound's identity. Additionally, the range of melting point and boiling point can provide information on the purity and molecular structure of the compound.
What are three physical properties used to identify compound?
Three physical properties used to identify compounds are melting point, boiling point, and density. These properties can be compared to known values of compounds to determine the identity of an unknown compound.
What is the usefulness of determinationof melting point?
The determination of melting point is useful for identifying substances by comparing the observed melting point to known values. It can help confirm the purity of a substance by assessing the sharpness of the melting point curve. Additionally, the melting point can provide information about the stability and potential applications of a compound.

How could you use the physical properties of melting and boiling point to identify a substance?
If you know the melting point and boiling point of a substance, you could look them up in a table to see what substances have those melting and boiling points. In practice, there are lots of other tests you'd probably want to do in addition, because in general there's no guarantee that an unknown substance is a single pure compound.
What is the probable identity of the unknown crystalline hydrate?
The probable identity of the unknown crystalline hydrate can be determined by conducting techniques such as X-ray crystallography, spectroscopy, and elemental analysis. These methods can provide information on the crystal structure, chemical composition, and properties of the compound, which can help in identifying the hydrate.
