Question

Why is the melting point of a substance very important?

Answer 1

Hey.

Here is the answer.

Melting point of a pure substance is fixed whereas for impures it varies over a range of temperature.


Melting point can be useful in determining whether the material is pure or not. If the melting point of any pure compound is known, then the melting point of the substance you have can be matched with the pure one. If the melting points are same it indicates that the substance you have is the same as the one that was compared with.

Thanks.
