the melting point of pure substances is always being sharp. it means that the boiling point it have it will boil at that point not some up or down but on same temperature in other words we say that it has no impurities because of impurities it boiling point varies and it has many other components and boiling point of every component is different so that why the boiling point of impure compounds varies or it don t have exact value and the pure compounds have same elements combine together and every molecule boil at particular point so it has sharp melting point or exact point

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.
Is boiling point is always same as the melting point?
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
Is a sharp melting point for a crystalline organic substance always indicates a pure single compound?
In general, a sharp melting point for a crystalline organic substance can suggest a pure single compound. However, impurities or different polymorphs can also affect the sharpness of the melting point. Additional analysis, such as TLC or NMR, may be needed to confirm the purity of the compound.
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
The term defined as the temperature at which a substance changes from a solid to a liquid state is called the melting point.
Why is it misleading to identify a solid compound just from a lone melting determination?
Identifying a compound based solely on its melting point is misleading because different compounds can have the same melting point. Additional tests, such as spectroscopic analysis or chromatography, are required to accurately determine the compound's identity. A single melting point determination is not sufficient as it could lead to a wrong conclusion about the compound present.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
What happens to neon during melting point?
There are a number of things that could happen to neon while it is at its melting point. It could melt.
How could the identify of a compound be established by melting point?
Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
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.
What was the first object to have a melting point?
objects just dont come up with melting points. to the smallest piece of iron to the largest the melting point is always going to be the same no matter what
How would you determine the purity of the solid crystals in crystallization?
One of the easier and more reliable ways to check if a solid compound is pure after re-crystallization is to check its melting point. Impurities will always lower the melting point of a sample, and the more impure, the lower the melting point will be. By checking the melting point of your sample with a reference value from a book or reliable internet source, it can be determined exactly how impure the sample is. If perhaps your compound is unknown, and thus are unable to obtain a reference value, you could obtain melting point of the sample, and then re-crystallize a few more times, obtaining a new melting point each time, until it is unchanged by re-crystallizing. This will of course decrease your yield, but if there is little fluctuation in your series of melting points, you can be sure you have a relatively pure sample.
Is boiling point is always same as the melting point?
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
To increase Melting and boiling point of Zinc what is to be done?
To increase MP and BP point of Zinc u should add some impurities in it. The addition of impurities always decreases the melting point .
What is another name for the freezing point of a material?
Another name for freezing point is melting pointsince the temperature at which a substance freezes is also the temperature at which it melts, going in the other direction.Freezing point could also be referred to as congelation point.
Can potassium chloride andsodium chloride be separated by sublimation?
No, because neither of them sublimate at 760 torr (1 atm). They melt. You could separate them by melting point, as NaCl has a melting point of 801ºC, but KCl has a melting point of 770ºC.
Which test or observation can be used to show that a sample of glucose is pure?
You could test its melting point, since pure glucose has a known melting point of 146oC.
