Answer 1

Answer #1

Yes because it contains impurities also which hampers and affect the melting point determination and the results also.

Also melting point of caeffine products are quite high

Caeffine has to be extracted first from its product in order to test it's melting point.

A student performs two melting-point determinations on a crystalline product. In one determination, the capillary tube contains a sample about 1−2 mm in height and the melting range is found to be 141−142°C. In the other determination, the sample height is 4−5 mm and the melting range is found to be 141−145°C. Explain the broader melting-point range observed for the second sample. The reported melting point for the compound is 143°C. Explain what may have caused the broader melting range...
