two substances,a and b have same melting point.How can you determine if they are the same without using any form of spectroscopy? Explain in detail.
Answered by Dr Russ
If they are the same compound then the melting point of a mixture will be the same as a and b. If a and b are different compounds then a mixture of the two will have a different (lower) melting point than a and b.

It is not a good idea to piggy back questions because it looks as though the original question has been answered, so one looks at the next.

I have answered the hexyl benzene question above.
